Fengy Cable is a cstom wire & cables manufacturer in China, our products include flexible cables, spiral cables, drag chain cables, power cords, extension cords, wire harnesses, etc.

The inner and outer coated epoxy composite steel pipe is coated inside and outside the modified epoxy resin powder. It has excellent comprehensive performance, especially the coating of epoxy composite steel pipe inside and outside the water supply, which has strong corrosion resistance and the external temperature is -40 ° C ~ 90 ° C. Applicable water delivery temperature is -30 ° C ~ 80 ° C, also has good chemical resistance and water resistance, in line with the evaluation of drinking water distribution equipment and protective materials.

The nature of the diagnostic cable fault is to determine whether the fault resistance is high impedance or low resistance; is it a flashover or a closed fault; is grounding, short circuit, disconnection, or a mixture of them; is single phase, two phase, or three Phase failure. The nature of the fault can be initially determined based on the phenomenon that occurs when the fault occurs.

Parallel failure is the guidance of the insulation between the outer skin or the conductor, and can not withstand the normal operating voltage. The actual combination of faults is many. Several types of faults are more likely to be: one opposite, two opposite and one phase broken and grounded. Power cable failure causes and detection technology Cable failures are defined as: no damage failure.

The inner and outer plastic coated composite steel pipe is a new type of pipe newly developed through years of research and experiment. The connection method of steel-plastic composite pressure pipe is similar to that of aluminum-plastic pipe. The pipe can be bent at a small angle. Therefore, it is not necessary to use pipe joints for small angle steering, mechanical flared crimping for large angle steering, and inner seal for connecting pipe fittings. deal with. The inner and outer coated steel pipes also have good insulation effect and strong resistance to interference. It is like a protective cover for cables in high-voltage power homework. It is safe and reliable for long-term use, and it does not cause leakage and other dangers.
