When paired with matching insulating covers, the clamps deliver reliable insulation shielding, lowering short-circuit and leakage risks for outdoor wiring projects. We stock aluminum, copper and copper-aluminum bimetal variants to fit dissimilar metal wire splicing, effectively mitigating galvanic corrosion between copper and aluminum cables.<\/p>\n<p><strong>Core Advantages<\/strong><\/p>\n<ul>\n<li><strong>Corrosion-Resistant Raw Material<\/strong> \u2014 High anti-oxidation aluminum alloy as standard; copper-aluminum transition models eliminate electrochemical corrosion at copper\u2013aluminum junctions, significantly extending outdoor service life.<\/li>\n<li><strong>Anti-Drop Integrated Structure<\/strong> \u2014 One-piece connected hardware prevents bolt and washer detachment during field installation, reducing rework risk.<\/li>\n<li><strong>Anti-Creep Arc Clamping Design<\/strong> \u2014 Large curved contact surfaces distribute clamping force evenly to suppress conductor creep deformation and prevent loosening from long-term wire stress and temperature swings.<\/li>\n<li><strong>Low-Resistance Tooth-Shaped Contact<\/strong> \u2014 Precision-machined tooth profiles reduce contact resistance for stable electrical conductivity and less heat buildup at wiring joints.<\/li>\n<\/ul>\n<p><strong>Certified Performance<\/strong><\/p>\n<ul>\n<li>Power frequency withstand voltage: \u226518kV, zero dielectric breakdown in 1-minute testing<\/li>\n<li>Insulation resistance: above 1.0\u00d710\u00b9\u00b2 \u03a9<\/li>\n<li>Maintains dependable performance after 1008 hours of artificial accelerated climate aging<\/li>\n<\/ul>\n<p><strong>Applications<\/strong> Overhead low-voltage distribution line tap-off and cable jointing; power grid upgrade and rural electrification; street lamp, monitoring and landscape lighting branch wiring; temporary power supply; copper-to-aluminum transition connections.<\/p>\n<p>Custom specifications and insulating cover sets are available.
