FAQ
Q: What is the JT crimp-type splice tube used for?
A: Used for mid-span splicing of copper conductors to repair broken wires or extend conductors while ensuring strength and electrical conductivity.
Q: What is the difference between JT and JY splice tubes?
A: JT: Pure copper, crimp-type, used for copper conductors
JY: Aluminum + steel, hydraulic-type, used for steel-core aluminum stranded wire (aluminum conductors)
Q: What is the difference between crimping and hydraulic pressing?
A: Crimping: Uses a manual crimping tool to create grooves; suitable for small-gauge copper wires
Hydraulic pressing: Uses a hydraulic press to compress the entire joint; suitable for large-gauge wires and high-voltage lines
Q: Can JT splice tubes be used on aluminum conductors?
A: No.
Direct connection between copper and aluminum causes electrochemical corrosion and thermal damage; aluminum wires must use JY or aluminum splice tubes.
Q: Can they be reused?
A: No.
Crimping causes permanent plastic deformation; they are for single-use only and cannot be disassembled and reconnected.
Q: How do I select the JT model?
A: Select directly based on the cross-sectional area of the copper conductor:
For example, 50mm² copper wire → JT-50.
