DFP Type 12/24/35kv Outdoor Cable Distribution Box

Product Introduction

DFW type cable distribution box is a kind of outdoor high-voltage electrical equipment of that rated voltage is 12/24 / 35kV, rated current is 630A , for the connection and cut of power cable.


Structure features 

This products adopts "high-performance hexafluoride load switch with SF6 insulation gas inside" and "shielded silicon rubber cables separable connector", with strong drop-out ability of active load and no-load cable current and strong closing ability of short-circuit current, what's more, we can install lightning arrester and ground fault indicator according to users' request.


Each ring connecting lines of this series of products are equipped with vacuum load switchgear or circuit breaker, any branch circuit is free to withdraw and put into operation, and other ring circuits are not affected; can install extra fuse on load switch, when one branch circuit has short-circuit accident, the fuse in this branch circuit can break accident circuit immediately, and impact load switch's release to let it trip, isolate accident circuit, which can ensure non-accident circuits' continuous power supply.


Standards 

◇ GB3804  3-36kv AC H.V. load switch

◇ GB311.1  insulation coordination of high-voltage power transmission equipment

◇ GB11033.2 basic technical requirements for less or equal to rated voltage 26 /35kV  power cable accessories 

◇ GB11032  AC gapless MOA


Normal operational conditions

1, Altitude: ≤ 2500m

2, Environmental temperature:-45°C ~ +40°Cthe maximum temperature ≤ 25 ℃㘰  

3, The place without recurrent severe vibration or corrosion


Suitable places

This products is widely used in cable distribution of 12/24/35 kv power system. Its connection method is easy, flexible and convenient, safe and reliable; main body uses 2mm stainless steel plate which is solid and durable. Portions with power adopts fully insulating and sealed structure. Use shielded silicon rubber cables separable connector, can withstand flooding, greatly improve reliability of power supply.

DFP Type 12/24/35kv Outdoor Cable Distribution Box


Product features

● all stainless steel casing , sealed, fully insulated, no exposed live body,

● maintenance-free

● anti-immersion of flood, anti-dirty, anti-condensation and cream, corrosion-resistant. make use of external semi-conductive composite silicone rubber cable connector, ensure personal safety.

● cable connector adopts advanced "later injection the insulating layer" technology, outside layer is uniform external shielding of 2mm thick, grounding resistance is less than 1000Ω, after assembly the front and rear connectors, the center distance is only 100mm which make the size of cable distribution box be further smaller, it is the most advanced prefabricated cable connector in the world.

● small size, easy to install, outlet and inlet lines are flexible, mostly can have eight circuits.
