Control cable storage and transportation should pay attention to these issues?

We first need to understand what is the control cable, control cable is a kind of cable to protect the circuit, the main material is polyvinyl chloride, has good insulation properties, this cable can be rated at 450/750 volts under normal operation, so it can be very good control of the operation of the circuit. Control cables are used in a wide range of applications, including some factories, mines and large energy sectors and so on. Control cable belongs to the electrical equipment cable, is one of the five categories of cable. Control cable manufacturers in the storage and transportation of cables need to pay attention to the problem: 1, the storage of cables in the warehouse shall not damage the insulation, corrosion of metal harmful gases. 2, try to avoid storing cables in the open air, the cable tray is not allowed to pave the way. 3, storage of cables, it is strictly prohibited to contact with acids, alkalis, mineral oils, they should be stored in isolation from corrosive substances. 4, it is strictly prohibited to fall from a high place in the transportation of the band cables or cable trays, especially in low temperatures (usually in low temperatures). Especially at low temperatures (generally at 5 ℃ and below), which may lead to cracking of the insulation and sheath. 5, in vehicles, ships and other means of transportation, cable trays should be fixed by appropriate methods to prevent collision or overturning to prevent mechanical damage to the cable. 6, the storage period of the cable to the product factory as a limit, the storage period is generally not more than one and a half years, and shall not exceed a maximum of two years. Control cable line common faults are mechanical damage, insulation damage, insulation moisture, insulation aging and deterioration, overvoltage, cable overheating faults. When the line occurs the above faults, should cut off the power supply of the faulty cable, looking for faults, check and analyze the faults, and then carry out repairs and tests, the cut out of the cut out, to be eliminated after the fault before the resumption of power supply.
