Tiankang BPGGPP2 frequency conversion cable

Tiankang BPGGPP2Variable frequency cable, BPGGP2 silicone rubber cable

The structure of a frequency conversion cable includes three main insulated wires and three neutral insulated wires. An inner winding layer, a copper strip layer, an outer winding layer, and an outer sheath layer are sequentially set outside the main insulated wires and neutral insulated wires to form a 3+3 core structure, which makes the cable have strong voltage impact resistance and can withstand pulse voltage during high-speed and frequent frequency conversion, providing good protection for frequency conversion electrical appliances

Tests include type tests, sampling tests, routine (factory) tests, inspections, etc. All types of tests should be conducted according to the methods specified in standards such as GB and IEC.
