What are Power Cables?

Modern power cables come in various sizes, materials, and types, each particularly adapted to its uses. Large single-insulated conductors are also sometimes called power cables in the industry.

Features of power cable

Features of the power cable

Power cables may be either fixed or detachable from the appliance. In the case of detachable leads, the appliance end of the power cable has a female connector to link it to the appliance to avoid the dangers of having a live protruding pin. Cables may also have twist-locking features or other attachments to prevent accidental disconnection at one or both ends. A cable set may include accessories such as fuses for overcurrent protection, a pilot lamp to indicate voltage or a leakage current detector. Power cables for sensitive instruments or audio/video equipment may also include a shield over the power conductors to minimize electromagnetic interference.

Constitution of Power Cable

Main part of the power cable

The main part of the power cable

Conductor — a conductive material that is constructed to carry electric current. A electrical wire or electrical cable, or other metal forms, is installed to convey electric current from one piece of electrical equipment to another or the ground.

Insulation and sheath are the components of a cable that protect the conductor. The insulation isolates the flow of electricity, and the sheath wraps around the outside of the cable to protect the conductors inside. The choice of material used for insulation and sheath can significantly impact a cable’s overall performance. The following will provide an overview of the most common materials used in cable manufacturing.

PVC (Polyvinyl Chloride)

PVC is the most common and cheapest option for a given cable design; it offers good flexibility, low cost, and reasonable durability. It also provides good resistance to Oil and water.

Polyvinyl Chloride


Natural rubber ensures flexibility, even at sub-zero temperatures. Rubber is waterproof, chemical resistant, extremely flexible, and retains its flexibility over a wide range of temperatures. Due to its high cost, synthetic rubber compounds are available to create more economical solutions which offer very similar performance.


For high or low temperature applications, operates from -50°C to +180°C. Excellent UV resistance and when exposed to fire does not produce any smoke or toxic gases. The soft material is however prone to damage and must be installed with care.


Power cable length measurement

Depending on the application, cable length in a power cable or cable set is a choice for the designer. Interpower offers standard length power cables and cable sets, as well as specialized lengths. When measuring all power cables and cable sets, Interpower uses a standard method of measurement.

When manufacturing power cables and cable sets, DelightFire follows North American and international standards, along with minimum and maximum lengths per country regulations and/or standards. It should be noted that there are application limits that need to be considered. For example, cables over 50 feet in the United States and Canada will have the amperage rating derated. For international applications, the derating depends on the application and the cable used in the assembly.

DelightFire measures its cable sets from the face of the connector to the face of the plug, not including the pins. DelightFire uses this method for all cable sets.

DelightFire measures its power cables from the face of the connector or plug, not including the pins, to the end of the cable. We use this method for all power cables.

The standard tolerances include the following:

Length Standard Tolerance
0–2.99 ft. (0–913mm) +/- 1 in. (25mm)
3–5.99 ft. (914–1827mm) +/- 2 in. (51mm)
6–11.99 ft. (1828–3656mm) +/- 3 in. (76mm)
12–19.99 ft. (3657–6095mm) +/- 4 in (102mm)
20–49.9 ft. (6096–15210 mm) +/- 6 in (152mm)
50+ (15240+ mm) +/- 12 in (305mm)

Types of Power Cables

According to the type of plug

Three plug power cord and two plug power cord are generally composed of three cores, wired for zero, fire, and ground; two plug power cord is composed of two cores, wired for zero and fire.

According to the type of current

DC and AC power cable, DC is the current direction does not change periodically from time to time for the current, but the current size may not be fixed, and produce waveforms. For example, a constant current is a type of DC. DC power cables are usually used for audio cables, solar panels, USB data cables, audio cables, device charging cables, printers, adapters, monitor charging cables, etc.

DC power cable drawing

AC power cables are cables that pass through higher voltage AC, which require uniform standards to obtain safety certification before they can be Official production, it is used in the AC power cord, usually in small appliances, communications, various mechanical equipment, mouse, keyboard, video, scanner, camera, TV, video capture box, speakers, mobile phones, audio, digital cameras, MP3, MP4, game consoles and other products.

According to the tail treatment

Tinned tail, IEC C13, IEC C7, IEC C5, etc. These are usually used in air conditioners, refrigerators, washing machines, rice cookers, induction cookers, electric frying pans, electric fans, irons, microwave ovens, computers, notebooks, scanners, video cameras, audio, digital cameras, lamps, various types of chargers and other large and small household appliances, power tools, and industrial electrical equipment.

According to the standard certification

CCC certification plug wire, UL certification plug wire, VDE certification plug wire, PCT certification plug wire, SASO certification plug wire, etc. CCC certification for the Chinese standard power cord plug, UL certification for the United States standard power cord plug, PCT certification for the Russian standard power cord plug, and SASO certification for the Saudi standard power cord plug.

Choose A Power Cable or Cable Set

Selecting the appropriate power cable or cable set is an essential step for equipment designers to ensure that their product may be used worldwide. Choosing a cable usually involves four steps:

Identify the Correct Power Cable Plug

The first choice concerns the plug pattern. As several plug patterns are used worldwide, determining the correct one is essential. When deciding on the correct plug pattern, remember that while some look similar, that does not mean it is the correct cable for the equipment.

Japanese Class plugs

For example, the North American and Japanese Class plugs look alike. However, North American cables do not carry the Japanese approval symbol and therefore should not be exported for use in Japan. The same applies to Japanese cables, which will not have North American approval.

Another example is the similarities in appearance in the Australian, Argentinean, and Chinese plug patterns, but again there are important differences between the three. Determine the Rating of the power cable or cable set.

Determine the power cable rating

It’s crucial to know the amperage and voltage rating that is required for the equipment being exported. Higher or lower amperage can mean a different plug pattern, even in the same country. Amperage requirements also affect the cable size.

Choose the Correct Cable

There are differences between North American and international cable, which are not interchangeable. North American cable cannot be used in countries with international cable standards and vice-versa.

For example, removing a North American plug from a cable set made with North American cable and replacing it with a Continental European plug will not make the cable set acceptable for Europe.

Choose the right connector

Choices for a connector may include an IEC 60320 connector or an inline country-specific socket. An advantage of using IEC 60320 components is that they can assist in making a product globally accessible. For example, an IEC 60320 connector can be attached to a detachable cable set with a country-specific plug. The connector will provide the power to the equipment by connecting with an IEC 60320 inlet in the equipment.


Power Cable Lettering

SVT power cable

S = Extra hard service (rated for 600V)

J = Junior (hard) service (rated for 300V)

V = Vacuum cable (rated for 300V)

P = Parallel cable

E = Elastomer jacket (UL or NEC only)

T = Thermoplastic jacket

O = Oil-resistant outer jacket

OO = Oil-resistant outer jacket and inner insulation

W = Weather and water-resistant – outdoor rated (note: this is NOT the same as Type W, another kind of portable cable)

Rating of power cables

Power cables or sets are rated according to the “weakest link.” This means that the plug, power cable, and connector are treated as separate components, and the component with the lowest Rating determines the Rating of the whole assembly. For example, a power cable set with a 15A plug and a 10A connector on a 13A power cable would have an overall rating of 10A.

Power Cable Applications

The power cable is a versatile product frequently used because of the wide variety of constructions available. With various constructions available, the oil-resistant and water-resistant capabilities are the most popular characteristics as their part of a large majority of the constructions.

Some of these applications include:

Heavy tools, Portable stage lights, Garage, Battery chargers, Flexing applications, When Oil and chemicals are present, Production lines, Manufacturing facilities, and Within process industries.

Typical application areas with stricter safety requirements include medical technology, stage and lighting, and computing equipment. For specialty equipment such as construction machinery, sound, and lighting equipment, emergency medical defibrillators, and electrical power tools used in locations without a convenient power source, extension cables are used to carry the electric current up to hundreds of feet away from an outlet.

International power cables and plug adapters are used in conjunction with electrical appliances in countries different from those in which they were designed to operate. Besides a cable with one end compatible with receptacles or a device from one country and the other end compatible with receptacles or devices from another country, a voltage converter is usually necessary, as well, to protect travelers’ electronic devices, such as laptops, from the differing voltages between the United States and places like Europe or Africa.
