In the international standard classification, electrical performance involves batteries and batteries, metal material testing, solar engineering, aerospace systems and operating devices, wireless communication, trams, electronic tubes, transformers, reactors, inductors, insulating materials, nondestructive testing, electrical devices, wires and cables, components and accessories for telecommunications equipment, audio, video and audio-visual engineering Integrated electronic components, agriculture and forestry, capacitors, insulation, kitchen equipment, piezoelectric and dielectric components for frequency control and selection, integrated circuits, microelectronics, ceramics, road vehicle devices, protective equipment, refrigeration technology, electricity, magnetism, electrical and magnetic measurement, textile products, floor non-woven fabrics, adhesives and adhesive products, semiconductor discrete devices Electric lamps and related devices, interface and interconnection equipment, electronic display devices, road vehicle internal combustion engines, telecommunications systems, electrical equipment components, filters, microprocessor systems, printed circuits and printed circuit boards, telecommunications terminal equipment, continuous handling equipment, switchgear and controllers, vocabulary, insulating fluids.

The electrical performance test includes the basic parameter test of conductor or insulation quality, such as conductor resistance, insulation resistance, correct value of dielectric loss angle, capacitance, etc. The higher the working voltage of the cable, the stricter the requirements for its electrical performance.

（1） DC resistance test of conductive core

The resistance of the cable of each nominal section shall not exceed a certain value, otherwise it will increase the core loss of the cable during use, resulting in cable heating, which will not only consume material and electric energy, accelerate the aging of plastic cable, but also bring danger to the reliability and stability of cable operation.

At present, double arm measuring bridge is commonly used.

（2） Insulation resistance test

The ratio of DC voltage U applied to insulation to leakage current I is called insulation resistance R. the insulation resistance of cable is mainly to judge the humidity and insulation quality of cable insulation layer.
