Product Description
The SC (JGA) series of sealed copper cable lugs (featuring an inspection window) manufactured by Yueqing Jasco Electric are cold-crimped terminals. Constructed from high-purity T2 copper, this series features a fully sealed design that delivers excellent electrical conductivity alongside superior oxidation and corrosion resistance. The built-in inspection window allows installers to visually verify that the copper conductor is fully inserted prior to crimping, thereby effectively preventing connection failures and streamlining on-site installation and inspection processes.
Available in a wide range of specifications, these terminals operate within a temperature range of -55°C to +150°C and maintain stable contact resistance after crimping. They are widely used for copper cable termination in applications such as switchgear, box-type transformers, solar power generation, and energy storage systems (ESS). Additionally, the company offers OEM/ODM customization and neutral packaging (unbranded export packaging) services.
