The 22–33kV Polyethylene Cable Spacer is designed to maintain proper spacing and alignment of overhead insulated or covered conductors in medium and high voltage distribution lines. Made from high-strength polyethylene, this high voltage cable spacer offers excellent electrical insulation, mechanical stability, and resistance to UV radiation and harsh outdoor environments. It effectively prevents conductor clashing, vibration damage, and phase-to-phase contact, improving the overall safety and reliability of overhead power systems.

Lines requiring phase spacing control
• Select the appropriate polyethylene cable spacer according to conductor size and system voltage (22kV or 33kV).
• Position the spacer between adjacent phase conductors at designed intervals along the span.
• Secure the spacer firmly using built-in locking or clamping structures.
• Ensure conductors are evenly spaced to prevent contact during wind-induced movement.
• Periodically inspect spacers during line maintenance to ensure long-term performance.
