PRODUCT SHORT DESCRIPTION
JY hydraulic compression splice sleeve for ACSR conductors (240/50/95/120), pure-aluminum tube with steel-insert for steel-reinforced cable. Hex-die crimped, low-loss joint.

PRODUCT DESCRIPTION

The JY hydraulic conductor splice sleeve is a compression connector used to join two lengths of ACSR (steel-reinforced aluminum conductor) on overhead transmission and distribution lines. Each sleeve consists of a pure-aluminum outer tube and, where required, an internal steel sleeve that grips the steel core, providing both mechanical strength and full electrical conductivity. The joint is completed with a hydraulic press and matched hexagonal dies, producing a compact, gas-tight splice that restores the conductor’s original current-carrying capacity and tensile strength. The JY range covers 240/40, 50/8, 95/15 and 120/20 and similar ACSR sizes.

Key Features
• True ACSR Construction — Aluminum outer tube plus steel inner sleeve grips both the aluminum strands and the steel core.
• Hydraulic Hex Crimp — Matched hexagonal dies produce a uniform, gas-tight, high-strength compression joint.
• Full Conductivity — Pure-aluminum tube restores ≥100% of the conductor’s electrical rating.
• High Tensile Strength — The steel insert maintains the conductor’s mechanical tension across the joint.
• Low Loss & Cool Running — Large contact area keeps resistance and operating temperature low.
• Corrosion Resistant — Pure aluminum and grease-filled options protect the joint from moisture and oxidation.
• Broad Size Range — Covers JY-240, JY-50, JY-95, JY-120 and other common ACSR sizes.
• Standardized — Manufactured to GB/T 2314 / IEC 61284 type compression-sleeve requirements.
