Different types of competitive silicone rubber insulators have different functions, and the structure height and creepage distance are also different. Competitive silicone rubber insulators are mainly used in substations, with good resistance to electrical corrosion, water repellency, tracking resistance and anti-aging properties, high tensile strength and flexural strength, anti-brittle fracture performance, high mechanical strength, shock resistance, good impact resistance, easy installation and maintenance, light weight.
Let's take a look at the improved technical parameters of competitive silicone rubber insulators.
1. Service life. According to the 15 to 20 years of successful operation experience of silicone rubber, the manufacturing technology and the mechanical parameters, physicochemical and physical level of the umbrella cover, our country can set the service life of the silicone rubber insulating material as 15 to 20 years.
Strictly control the quality of raw materials, can not be shoddy. Continuously improve, optimize and improve the formula on the basis of operating experience. This is especially true for the use of DC silicone rubber insulators, and strive to increase its service life to thirty years.
2. Optimize the formula and forming process. Accumulate operating experience under special operating conditions such as strong ultraviolet rays, high cold and high humidity, optimize and perfect the formula, and require the umbrella cover to have weather resistance to prevent rapid deterioration caused by high and low temperature, ozone, humidity, ultraviolet light and other conditions. The competitive silicone rubber insulators used in the 500kw and below lines are integrally injection molded in one injection, and the silicone rubber used in the 750kw and 1000kw lines is integrally injection molded in a second time.
