Selection of wire and cable models:
When selecting wires and cables, consideration should be given to their intended use, installation conditions, and safety. For example:
According to different purposes, power cables, overhead insulated cables, control cables, etc. can be selected;
According to different laying conditions, general plastic insulated cables, steel tape armored cables, steel wire armored cables, anti-corrosion cables, etc. can be selected;
According to safety requirements, non combustible cables, flame-retardant cables, halogen-free flame-retardant cables, fire-resistant cables, etc. can be selected.
Transportation and storage of wires and cables:
1. It is strictly prohibited to throw cables or cable reels containing cables from a height during transportation, especially at lower temperatures (usually around 5 ℃ or below). Throwing or dropping cables may cause insulation and sheath cracking.
2. Try to avoid storing cables in an exposed manner in the open air as much as possible, and cable reels are not allowed to be laid flat.
3. When lifting packaging, it is strictly prohibited to lift several plates at the same time. On vehicles, ships, and other transportation vehicles, cable reels should be secured using appropriate methods to prevent collisions or tipping over, in order to prevent mechanical damage to the cables.
4. Cables must not come into contact with acids, alkalis, and mineral oils, and must be stored separately from these corrosive substances There shall be no harmful gases that damage insulation or corrode metals in the warehouse where cables are stored.
5. During the storage period, the cable should be rolled regularly (once every 3 months in summer, and may be extended at discretion in other seasons). When rolling, roll the storage tray upside down to prevent the bottom from getting damp and rotting. When storing, it is important to regularly pay attention to whether the cable head is intact and undamaged.
6. The storage period of cables is limited to the product's factory period, generally not exceeding one and a half years, and the longest not exceeding two years.
