JBTL type parallel groove clamp

The JBTL-Type Parallel Groove Clamp is a copper-aluminum transition connector designed for joining aluminum conductors to copper busbars or terminals in overhead lines and substations. Its friction-welded copper-aluminum plate prevents galvanic corrosion and ensures stable electrical contact. The clamp body is made of high-strength aluminum alloy with stainless steel hardware; all ferrous parts are hot-dip galvanized. The parallel groove design applies uniform pressure on both conductors, protecting them from damage while maintaining low contact resistance. Easy to install with standard tools, the JBTL clamp is ideal for branch connections and non-tension joints in distribution and transmission systems.
