FAQ
Q: What is the JY hydraulic Compression Splice used for?
A: Used for mid-span splicing of steel-core aluminum stranded wire to repair broken wires or extend conductors, while ensuring mechanical strength and electrical conductivity.
Q: What is the difference between the JY Compression Splice and the parallel groove clamp?
A: JY: Hydraulic crimping, permanent splice; high strength and good conductivity; used for mid-span joints on main lines
Splice clamps: Bolt-type, primarily used for temporary splices, jumpers, and branch connections
Q: Why do steel-core aluminum stranded wires use a “aluminum tube + steel tube” double-layer structure?
A: Steel tube: Connects the steel core and bears the primary mechanical tensile force
Aluminum tube: Connects the aluminum strands and handles electrical conductivity
This separates mechanical stress from electrical conductivity, making the connection safer and more reliable.
Q: Can JY splicing tubes be reused?
A: No.
They are single-use crimping fittings; once crimped, they undergo plastic deformation and cannot be disassembled and reused.
Q: What precautions should be taken during crimping?
A: The conductors must be thoroughly cleaned and inserted fully into position.
Use dies and a hydraulic press of the appropriate specifications.
Crimp according to the specified sequence to ensure the number and depth of crimp marks meet requirements.
The steel core and aluminum strands must not be crimped in the wrong positions.
