First of all, sufficient preparations must be made before laying the cable. Before winter construction arrives, relevant construction personnel should be organized to learn construction measures and preventive measures, and be familiar with construction drawings and technical documents related to cable laying. We also formulate a strict winter construction management system, strictly implement the regulations, specifications, and formulated construction measures and preventive measures related to winter construction to ensure that people, machines, materials, and materials can survive the winter smoothly, and to ensure that the project quality and project progress are not affected. Then make a material plan based on the established construction measures and preventive measures. The materials department should make sure the supply of required materials is done according to the plan, including insulation materials, antifreeze, coldproof, anti-skid, heating materials, etc., as well as erection related materials. Materials needed for the facility. And ensure that the construction roads are smooth, ice and snow are removed in time, and the working surface does not freeze.

Secondly, during the cable laying process, you must pay attention to everything and be ready at all times. For example, due to low temperatures in winter, when enough snow accumulates, the surface is easily covered with snow and ice. When the weight of the ice exceeds the capacity of the wires and cables, the wires and cables are placed overhead. This can easily cause the cable to tilt the transmission tower or pull down the utility pole, or the cable itself to break. So, in order to prevent this from happening, when choosing materials, you should pay attention to choosing cables that can withstand the cold.

Third, if open-air operations are carried out when the temperature is below -5 degrees, a heating lounge should be set up near the construction site, and the heating facilities should comply with fire prevention regulations. Heating and heating facilities must hang clear signs to prevent personnel from being burned. Fourth, when the ambient temperature of the cable storage location is lower than the cable's usage conditions, do not lay the cable. Wait until the cable is stored in a warm place for 24 hours before laying it.

In short, under very low temperature conditions, cable laying is generally not encouraged or even allowed. Especially in northern my country, the temperature is lower in winter, so except for necessary accident repairs, cable laying projects should be avoided as much as possible. In addition, as modern buildings become more advanced, higher requirements are put forward for cable laying in winter. Research needs to be conducted from the perspectives of reducing engineering construction costs and improving laying work efficiency, thereby improving the comprehensive competitiveness of wire and cable manufacturing enterprises.
