We all know that product selection is one of the key steps to ensure the successful implementation of the project, especially for insulation protection products in the power industry, such as PE overhead line cover.
The most important point in selecting PE overhead power line cover is to measure and confirm the outer diameter of the bare conductor to ensure that the inner diameter of the PE overhead line cover matches the outer diameter of the bare conductor. The inner diameter of the insulation overhead line cover should be slightly larger than the conductor diameter to facilitate the installation of the conductor and future maintenance operations.
