The 10–15kV Polyethylene Cable Spacer is designed to maintain proper spacing and alignment of conductors in overhead power distribution systems. Made from high-strength polyethylene material, this high voltage polyethylene cable spacer provides excellent insulation performance, mechanical strength, and resistance to environmental aging.
The 10-15kV polyethylene cable spacer for overhead lines helps prevent conductor clashing, reduces vibration, and improves overall line stability. It is widely used in medium-voltage power distribution networks where safe conductor separation and long-term reliability are required.
