PE electrical corrugated pipes are suitable for underground wire and cable sheathing in various power and communication fields such as industry, construction, and transportation. The corrugated structure has excellent flexibility and can adapt to a certain degree of uneven ground settlement. Meanwhile, the inner wall of the corrugated pipe is smooth with a low friction coefficient, which is beneficial to cable laying and protection. Its good insulation performance provides reliable guarantee for safe power transmission. In addition, it can withstand a certain external pressure and has good impact resistance.
