Abstract

The invention relates to EPDM (Ethylene-Propylene-Diene Monomer) compound rubber which is characterized by comprising the following raw materials: EPDM rubber, calcined argil, stearic acid, anti-aging agent, talcum powder, zinc oxide, anti-aging agent, vulcanizing agent, accelerating agent, plasticizer and high-pressure cable oil. The EPDM compound rubber disclosed by the invention has excellent ozone resistance, thermal-ageing resistance, weather resistance, electric insulation property and corona resistance and is particularly can be used for manufacturing high-pressure and extra-high-pressure electric insulation products.

Description

technical field [0001] The invention relates to a new material used for insulation of power cable accessories, in particular, it is a EPDM compound rubber. Background technique [0002] With the development of the national power industry, more and more high-voltage and ultra-high-voltage power systems are being built. Correspondingly, the voltage level of the supporting power cable accessories is getting higher and higher. Now the 110 kV power cable accessories have been domestically produced, and the 220 The localization of kV power cable accessories is being gradually promoted, and some domestic manufacturers are already developing 500 kV and 750 kV extra-high voltage power cable accessories. At present, most of the raw materials for domestically produced 110 kV and 220 kV power cable accessories are made of silicone rubber, but silicone rubber also has some disadvantages, such as poor tensile strength, only about 7 MPa, and low dielectric strength, which can only reach 20...
