JY _ JYD Series Conductor Splice Sleeve

Product Overview

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. Operating as a source manufacturing plant, we supply a full spectrum of standard sizes and offer tailor-made production to satisfy unique cable dimensions and project technical demands for overseas engineering contractors, power wholesalers and bulk B2B purchasers.

Core Product Advantages

Premium Anti-Corrosion Aluminum Raw Material

High-purity forged aluminum alloy delivers outstanding oxidation resistance. The finished sleeve resists rusting brought on by long-term outdoor UV exposure, rain erosion and coastal salt spray, cutting corrosion-induced connection faults and lengthening outdoor service life.

Stable Mechanical Tensile Performance

Precision dimension control ensures uniform stress distribution after hydraulic crimping. The splice joint can bear the rated pulling force of overhead lines, resisting slippage and breakage triggered by wind vibration, temperature fluctuation and external mechanical impact.

Low Contact Resistance for Reliable Power Transmission

Smooth inner wall surface creates tight metal contact with conductors post crimping, lowering contact resistance, restraining excessive heat buildup at splicing spots and mitigating power loss and overheating safety hazards under sustained operating load.

Specialized Drainage Design for JYD Models

Drainage holes built into JYD-type sleeves realize effective liquid drainage for high-voltage overhead lines, preventing internal moisture buildup that would degrade insulation performance and trigger line breakdown risks.

Straightforward Field Installation

Compatible with mainstream hydraulic crimping tools on the market; standardized inner bore sizes align with common conductor gauges to streamline on-site construction workflows and reduce installation labor hours.
