Product Features:
A simple, convenient and fast assembly way. In view of human body structure. Camber designed to fit the finger on the tangent part, and it is very comfortable for operating person by the anti-skidding measure
It is ensured the same lifetime as PV modules by innovative structure of plus-minus terminal and stable low contact resistant. According to the TUV test standard, having more than 30 years fine effciency of electric conduction, the contact resistance of JD junction boxes is lower 0.3mΩ , saving 52% resistance costing compared with the general structure.

Great carrying capacity of heavy current and high voltage.
Fine design of self-locking, and outstanding ability of resisting the mechanical shock.
Excellent seal design free from dust and water with IP65 level.
Eximious plastic material meets the UL94-V0 level of fire rating, good performances of waterproofanti-aging and uvioresistant features, and fits for the long term usage outdoors.
