Product description

DFW-12 Outdoor switch box is a new generation of cable distribution device, which is developed, designed and produced by our own company based on the needs of the electricity marketing.

It consist of 12kV cable accessories, secondary components and enclosure and flexibly take the advantage of series and paralleling, it can be assembled as per customer requirement.

It realizes the characteristics of full sealing, full protecton, all insulation, anti-condensaton, dust-proof, corrossion resistance, free maintenance. It can be running normally outdoor.
