Property Specification
Type: Copper Parallel Groove Clamp (CUPG Series)
Features: Forged from high-purity copper, this clamp incorporates transverse serrated grooves to maximize surface contact and lower resistance. It utilizes stainless steel bolts paired with Belleville spring washers to maintain consistent pressure and prevent thermal ratcheting under fluctuating cyclic electrical loads.
Applications: Engineered specifically for copper-to-copper connections, joining two parallel bare conductors (either stranded wire or solid rods) and facilitating branch or tap-off distribution lines.
