JY and JYD series conductor splice sleeves are core hydraulic crimp-type power fittings designed for butt splicing of overhead aluminum or aluminum alloy conductors. After hydraulic compression, they reliably transmit electric current and bear the tensile load of power lines, widely applied for wire jointing during grid construction, line overhaul, broken conductor repair and circuit extension projects. The JYD variant with drainage holes fits special high-voltage line drainage requirements.

Core Advantages

• Premium Anti-Corrosion Aluminum — High-purity forged aluminum alloy with excellent oxidation resistance, resisting rust from outdoor UV, rain and coastal salt spray for extended service life.
• Stable Mechanical Tensile Performance — Precision dimension control ensures uniform stress distribution after hydraulic crimping; the joint bears the rated pulling force of overhead lines, resisting slippage and breakage from wind vibration and temperature fluctuation.
• Low Contact Resistance — Smooth inner walls create tight metal contact with conductors after crimping, lowering contact resistance and preventing overheating and power loss under sustained load.
• JYD Drainage Design — Built-in drainage holes prevent internal moisture buildup that could degrade insulation and cause line breakdown.
• Easy Field Installation — Compatible with mainstream hydraulic crimping tools; standardized bore sizes align with common conductor gauges.
