With the promotion of the market economy of electric power equipment accessories, people are more and more dependent on electricity, and the reliability of the power supply is also getting higher and higher. 10-35KV high-voltage cable is the main channel for urban power supply. The links of production and transportation rely heavily on special cable terminations and cable joints, so cable accessories are necessary equipment for power transmission.
The heat shrinkable cable technology used uses high-energy ray radiation to make the cable termination material expansion before the heat and then molding. However, due to the limitation of materials and the influence of the breathing effect, heat shrinkable cable accessories usually have a service life of 4-5 years. The service life of the cable is more than 20 years. Cables and matching cable accessories have different lifespans. It will seriously affect the long-term stable operation of the power supply system.
The new type liquid silicone rubber used to manufacture cold-shrinkable cables has excellent high elasticity, weather resistance, and insulation properties.It solves the problem of life with the cable accessories produced by it, which can be completely compatible with the cablelife matching.Therefore, cold-shrinkable cable accessories will inevitably replace heat-shrinkable cable accessories, and the application of cold-shrinkable cable liquid silicone rubber to cable accessories will also become mainstream.
Other properties of electric power LSR are as follows:
Anti-aging performance, and excellent corrosion resistance, which can effectively improve the service life of cable accessories;
It has the characteristics of inorganic materials, and has strong electrical properties such as resistance to electrical corrosion and leakage, ensuring more reliable operation of cable accessories;
The applicable temperature range is relatively wide and it can work at -55 degrees to 250 degrees.
With good hydrophobicity, it can be applied to a variety of environments, such as coastal salt, fog, humidity, serious pollution, etc.; it greatly improves the quality of power cable accessories.
