What factors affect the life of high temperature resistant silicone wire

High temperature resistant silicone wire has high temperature resistance and long life. Although the high temperature resistant silicone wire is characterized by a long service life, if the high temperature resistant silicone wire is not paid attention to during use, it will also shorten the life of the high temperature resistant silicone wire. Let’s take a look at the factors that affect the life of the high temperature resistant silicone wire. ?

 1. Destructive factors from external forces. For example, non-standard construction during cable laying and installation can easily cause mechanical damage; civil construction on directly buried cables can also easily cause cable damage. Sometimes if the damage is not serious, it will take months or even years for the damaged part to be completely broken down to form a fault. Sometimes if the damage is serious, a short-circuit fault may occur, which directly affects the safe production of power users.

 2. Moisture factors on the insulating layer. This is also a common situation, which usually occurs at cable joints in direct burial or drainage pipes. For example, if a cable connector is unqualified in a humid climate, the connector will enter water or be mixed with steam, which will form water vapor branches in the electric field for a long time, which will gradually reduce the insulation strength of the cable and cause the cable to fail.

 3. Chemical corrosion factors. Silica gel wires buried directly under the action of acid and alkali often cause corrosion of the cable armor, lead skin or outer sheath, and the protective layer will fail due to chemical corrosion or electrolytic corrosion for a long time, and the insulation will be reduced, which can also cause the cable malfunction.
