Hi,
thanks for watching our video about 400v underground termination .
UNDERGROUND CABLE TERMINATION system: In compression terminations, the uninsulated conductor is inserted into a “box,” and the connection is made using screws, flat straps, or other mechanisms that compress the conductor.
Application: Commonly used in low-voltage circuit breakers and other electrical equipment.
Crimp Connections:
Description: Crimp connections use terminals with tubular openings. The cable conductors are placed inside the tube, which is then mechanically pressed or deformed to create a secure connection.
Variants: Available as butt splices, ring lugs, and spade lugs.
Quality Control: Calibrated crimping tools ensure proper connections, especially for safety-related circuits.
Soldered Connections:
Description: Like conductors of cables are soldered together or into connectors to form a physically secure, low-resistance termination.
Application: Infrequently used except for specific applications (e.g., military-type connectors).
Wire-Wrapping Connections:
Description: Uninsulated solid conductors are wrapped around a rectangular metal post with significant force. The deformation of the post ensures a secure electrical connection.
Common Use: Found internally in instrumentation, control equipment, and telephone circuit distribution boxes.
