Product overview
DFW-12 outdoor high-voltage cable adapter box is used for rated voltage 10kV, rated current is not more than 630A AC cable network, used in commercial centers, industrial parks, residential communities, streets, airports, docks, subways and urban densely populated areas and other distribution network cable connection, especially suitable for urban network transformation
It has the following characteristics:
1, all metal steel plate, or stainless steel plate, thickness of 2mm shell, to ensure that 20 years do not remove paint;
2, outdoor all-weather, full protection structure, suitable for high temperature, cold, flood soaking high dust areas;
3, all green completely closed, high voltage live parts are all silicone rubber or prefabricated connectors, sealed;
4, compact structure, small size, easy installation, maintenance-free;
5, flexible configuration, and SF6 load switch to form a ring network power supply;
6, one-time investment is small, reduce the length of the cable, does not occupy the building area, save money.
