summary

The contact box adopts epoxy resin structure, which is used for various handcart type switch cabinets to play the role of insulation isolation and connection transition. The installation center distance is 250mm, the rated voltage is 10kV, and the current is 2500A ~ 3150A. Under the rated current, the temperature rise at the end of the outlet should not exceed 65 ℃ under long-term operation.
