Catenary Parts - Parallel Groove Clamp Performance

(1) connector parallel groove Electrical properties
1) After the overload electric heat cycle test, the resistance between the two ends of the connection between groove clamp and the wire should not be greater than the resistance of the connected wire of the same length.
2) The temperature rise of the connection between parallel groove and the wire should not be greater than the temperature rise of the connected wire.
3) The current carrying capacity of parallel groove clamp connector should not be less than the current carrying capacity of the connected wire.
(2) pg clamp connector Mechanical properties
1) The gripping load after crimping between the contact wire electrical connection pg clamps and the soft copper stranded wire is not less than 4.0kN.
2) The sliding load between the contact wire electrical connection single bolt parallel groove connector and the contact wire is not less than 4.0kN.
