We have rich experience in the operation of wire and cable. The outer skin of wire and cable products is mostly environmentally friendly plastic (PVC) or rubber. When the outer skin is in a sub-zero environment, it will become hard and the entire wire and cable product line body will be damaged. Hard and brittle, the skin may fall off and be damaged even under slight external force. Therefore, especially in the north, the following points should be paid attention to in the protection of cables:
1. Mobile transportation
Whether it is moving or when the product is loaded on a transportation tool at the factory, it needs warm and protective measures. For example, use enclosed transportation tools to prevent the product from being directly exposed; padded the product with a layer of soft cushion, such as bedding or other soft foam, etc.; handle with care when moving and loading, do not rough load, and avoid product bending is too big. When arriving at the destination or construction site, it is best for the product supplier to send personnel to supervise it to prevent rough operations during product unloading.
2. Storage
It is best to store the product indoors, while laying a layer of isolation on the surface of the storage, such as wood, bedding, foam, etc., to prevent the product from freezing and damp, and to prevent the product from directly contacting the ground and scratching the wire and cable sheath The phenomenon, handle with care.
3. Product laying and installation
It is best to choose to work under the condition of warmer temperature in the middle and afternoon, if possible, use heaters and other equipment to "warm up" the product in advance before use, so that the product can reach the best performance state. If it is buried in the ground, a protective layer such as cloth or foam can be laid in the cable trench in advance. If you are wearing a pipe, you must first ensure that the inside and outside of the pipe are smooth, so that the wires will not be scratched. Special attention should be paid to iron pipes. When purchasing qualified iron pipes, there may be a large number of sharp raised points in the low-quality iron pipes, which may scratch the outer skin of the wires.
When working outdoors below zero, you should check carefully after installation to see if the cable is in good condition. If the cable product goes wrong, the impact will be more serious. We must regularly carry out line safety inspections. For wires, electrical equipment, etc., please ask professionals to conduct a thorough inspection at least once a year, especially for circuits with long service life at the joints. If unsafe conditions such as wire aging, damage, poor insulation, etc. are found, they must be repaired and replaced in time to ensure electricity use. Safety. Therefore, we must guard against unburned, and strive to do every detail.
