VS-PE is designed for insulation and protection of bare conductors in overhead power line systems, especially where weather resistance, electrical insulation and fast installation are required.
Typical applications include:
Bare overhead conductor insulation protection
Outdoor overhead power line covering
Electrical insulation for exposed conductor sections
Protection of conductors in areas requiring weather-resistant insulation
Power line maintenance and retrofit projects
Short-duration outage construction where fast installation is required
Selecting the correct PE overhead line cover model is important for safe and reliable insulation protection. Before selection, measure the outside diameter of the bare conductor and choose a cover size with an inner diameter that matches the conductor size.
The inner diameter of the overhead line cover should be slightly larger than the conductor diameter to support smooth installation and future maintenance. For higher voltage applications, select the corresponding model with sealant in the locking groove.
Confirm the conductor outside diameter and select the correct VS-PE cover size.
Clean the conductor surface and remove dust, oil or other contaminants if necessary.
Open the locking groove and position the cover over the bare conductor section.
Press the cover into place along the conductor length until the locking groove is fully closed.
For models with sealant in the locking groove, make sure the groove is properly closed to support sealing performance.
Check that the cover is fully seated and provides continuous insulation coverage over the required area.
VS-PE provides a fast, heat-free solution for bare conductor insulation protection in overhead power line systems. Its radiation crosslinked polyolefin material delivers weather resistance, electrical insulation, anti-aging performance and mechanical protection.
