电力管是采用PE（改性聚乙烯）进行热浸塑或环氧树脂进行内外涂覆的产品，具有优良的耐腐蚀性能。同时涂层本身还具有良好的电气绝缘性，不会产生电蚀。吸水率低，机械强度高，摩擦系数小，能够达到长期使用的目的。还能有效的防止植物根系及土壤环境应力的破坏等。
Electric power pipe is a kind of product which uses PE (modified polyethylene) for hot dipping or epoxy resin for internal and external coating. It has excellent corrosion resistance. At the same time, the coating itself also has good electrical insulation and will not produce corrosion. Low water absorption, high mechanical strength, low friction coefficient, can achieve the purpose of long-term use. It can also effectively prevent the damage of plant roots and soil environmental stress.
