Wedge Type Insulation Strain Clamp

NXL-1 Wedge Type Insulation Strain Clamp

Suitable for conductor cross-sections of 35–50 mm², specifically designed for tension mounting of 10 kV overhead insulated conductors. Requires stripping of the end insulation layer; suitable for securing insulated conductors in rural feeder lines and streetlight circuits. Aluminum alloy clamp body + insulated cover, providing strong grip and stable connection; a universal tension clamp for light-load insulated lines.

NXL-1 Wedge Type Insulation Strain Clamp

Compatibility: Specifically designed for 35–50 mm² 10 kV overhead insulated conductors; matches corresponding cable outer diameters with excellent clamping adaptability.
Stripping Length: Features a 225 mm stripping allowance to ensure effective engagement of the wedge clamping section while preventing damage to the insulation layer during clamping.
Dimensions: Overall structural dimensions are compatible with installation spaces for low-voltage tensioning suspension points, offering ample clearance for assembly.
Mechanical Load: Rated breaking strength of 7.4 kN meets tension-bearing requirements for overhead lines, preventing slippage or failure during operation.
Product Weight: Lightweight design reduces the load on pole/tower suspension points and facilitates installation during outdoor high-altitude work.

Features of Wedge Type Insulation Strain Clamp

Material: Manufactured from a single-piece, high-strength die-cast aluminum alloy blank; lightweight with a yield strength tailored to the tension requirements of low-voltage insulated conductors.
Manufacturing Process: Precision milling of the wedge cavity's inclined surface following die-casting; the wedge taper matches the self-locking structure, ensuring uniform clamping force without damaging the cable's insulating sheath.
Corrosion Resistance: Surface undergoes comprehensive passivation and anti-rust treatment; resistant to UV-induced aging and oxidation caused by outdoor moisture.
Standards: Complies with GB/T 2314 and GB/T 2315 technical requirements for electric power fittings; passes factory acceptance tests for tension grip strength and fatigue tensile performance.
