DFW SERIES CABLE JUNCTION BOX

DFW SERIES CABLE JUNCTION BOX

The DFW series cable junction box (also known as cable branch box) is divided into two types: with switch and without switch. It is an outdoor high-voltage electrical equipment with a rated voltage of 12KV and a rated current of 630A, used for connecting and tapping power cables.
DFW series high-voltage cable junction boxes are composed of electrical elements, secondary elements and boxes, such as electrified touchable shielded silicone rubber cable connectors, cable accessories, SF6 load switches or ring network cabinets, vacuum circuit breakers, etc. They fully and flexibly use the advantages of cable connectors in series and parallel connection, and can be reliably combined according to user needs. They realize the characteristics of full sealing, full protection, full insulation, anti condensation, dust prevention, corrosion resistance, and maintenance free, and can operate outdoors all day long.

Material selection for high-voltage cable junction box: Cable junction box with switch:

1. Cold plate spraying 2, stainless steel plate spraying

3. Wooden decorative landscape type 4, non-metallic landscape type

5. SMC non-metallic composite material without switch cable distribution box:

1. Cold plate spraying 2, stainless steel plate spraying
