Study on Ethylene Propylene Diene Monomer Insulation Rubber for Electric Submersible Pump Cables

基于对电动潜油泵电缆用绝缘材料三元乙丙橡胶的研究,通过三元乙丙橡胶与防老体系、增塑体系、补强体系、硫化剂等配合体系的试验,研制出的电动潜油泵电缆用三元乙丙橡胶硫化胶的抗张强度大于14 MPa,体积电阻率大于1.0×10^(15)Ω·cm。产品试验结果表明,该材料具有良好的机械性能、电性能和耐油性能,各项性能指标均能达到电动潜油泵电缆的技术要求,尤其在耐油性能、防水性能等方面具有明显优势。

Based on the research of ethylene propylene diene monomer,the insulation material for electric submersible pump cables.The tests of ethylene propylene diene monomer,aging prevention system,plasticizing system,reinforcing system and vulcanizing agent were emphasized.The tensile strength of ethylene propylene diene monomer vulcanizate for submersible pump cables was over 12 MPa,and its volume resistivity was over 1.0×10^(15)Ω·cm.Through the product test,results showed that the material had good mechanical properties,electrical properties and oil resistance,and all the performance indexes fully met the technical requirements of electric submersible pump cables,especially in terms of oil resistance and waterproof performance had obvious advantages.
