Control cabling failures are common mechanical damage, insulation damage, wet insulation, insulation aging deterioration, over-voltage, cable overheating fault. When the failure occurs, the line should be cut off the power to the faulty cable, find the point of failure, inspection and analysis of the fault, and then repair and testing, the mutilation of circumcision, until the fault is cleared only after power is restored. Wire and cable derivative / new products is mainly due to the convenience and lower equipment costs and other requirements of the applications, application requirements and equipment, and the use of new materials, special materials, or to change the product mix, or to improve the process requirements, or to different The cultivars product combination. Product main features are: many different specifications, a wide range of applications, the use of voltage 1kV and more, in the face of special occasions continue to rise to new products, such as fire-resistant cable, flame retardant cable, LSZH / LSF halogen cable, anti-termite, anti-mouse cable, oil / cold / temperature / wear-resistant cable, medical / agricultural / mining cable, thin-walled wire.
