In winter, many construction workers will find that when laying and installing electric wires and cables, they often find that some wire and cable products with good quality often cause stiffening of the wire and insulation and peeling of the insulation. Many construction workers think that the wire and cable products themselves. There was a quality problem, and the cable factory insisted that the product was tested at the factory and it was a qualified product, which often led to misunderstandings between the two parties.
In fact, it was not the quality of the product itself that caused the problem but it was due to the cold winter. The wire and cable products are mostly made of ordinary plastic (PVC) 24-hour hot wire: or rubber. When they are in sub-zero temperatures, they will harden. The entire wire and cable product line will become hard and brittle, causing the skin to be In the case of slight external force, shedding damage will occur. In winter, especially in northern regions, the outdoor temperature is often below zero, and the surface temperature may be lower. Therefore, if the wire and cable products are placed outdoors or directly on the surface, the outer skin of the product may fall off. So how do we prevent the wire and cable from falling off in winter? Take the following measures from each stage -
1. Shipment: When the product is shipped to the transportation tool, warming and protection measures are required. For example, use a closed transportation tool to prevent the product from being directly exposed; give the product a cushion, such as bedding or other soft foam; hold gently when loading, and do not rough load, and avoid bending the product. Big.
2. When arriving at the destination or construction site, it is advisable for product suppliers to station personnel to supervise and prevent rough handling behavior during product unloading. 24-hour hotline:
3. Storage: It is best to store the product indoors. At the same time, store a layer of insulation 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 contacting the ground directly. Cable skin scratch phenomenon, gently handle.
4. 24-hour hotline for product installation and installation: It is best to choose to operate under warmer temperatures in the middle and afternoon. If there are conditions, use warm air blower and other equipment to warm up the product in advance before use to make the product reach the best. Performance status. If it is buried in the ground, it can be covered with a protective layer in advance in the cable trench, such as cloth, foam. If it is wearing a pipe, the smoothness of the inside and outside of the pipe must be ensured in advance so that the electric wire will not be scratched. Iron pipes must pay particular attention to the selection of quality qualified iron pipes. Poor quality iron pipes may have a large number of sharp protrusions, which may cause scratches on the outer wires of the wires.
All in all, in the winter, the wire and cable will become very fragile, and it is also necessary for us to “careâ€.
