XDFW Cable Distribution Box:
XDFW high voltage cable distribution box is widely used for node connection in 35kV and 10kV cable systems. It is the main electric equipment to collect and distribute cables from the switch cabinet. The cable connectors are covered and insulated by imported top-quality rubber, and no any electrified part is exposed. The switch (if has) of the cable distribution box is SF6 insulating load switch.
XDFW cable distribution box is used outdoor. It is safe, reliable and maintenance- free. IP code is IP33. The connectors underground is resistant to flood inundation. This series of product is widely used for the power distribution networks of urban industrial district, residential district, commercial center, mines, and steel, automobile, petroleum, chemical and cement enterprises, especially suitable for urban power network reconstruction. It significantly reduces the costs of electrical equipment and cables, and improves the power supply reliability.
American Style Cable Distribution Box:
American style cable distribution box features excellent performance, normalized design and beautiful exterior. It is widely used for cable engineering equipment in cable distribution systems. It has received wide recognition from industrial parks, residence districts, urban populated regions, commercial centers and high-rise buildings. It is narrow, flexible, overall-insulated and overall-sealed. Based on different rated currents, it can be classified into “600A major loop” and “200A branch loop”. “600A major loop” adopts screw-in type bolts for connection, and “200A branch loop” uses socket + plug type connection with load sockets and plugs.
Working conditions:
1. Ambient temperature: +40℃ ~ -30℃。
2. Wind speed: 34m/s (≤700Pa)
3. Humidity: average daily humidity ≤ 95%, average monthly humidity ≤ 95%
4. Shockproof level: horizontal acceleration ≤ 0.4m/s2, vertical acceleration ≤ 0.15 m/s2
5. Gradient: ≤ 3°
6. Installation environment: no corrosive or inflammable gas or vapor, and no severe vibration
Remark: please consult us if clients have other different conditions

Cable Distribution Box with SF6 Load Switch:
This series of cable distribution box both reserves the advantages of traditional cable distribution box and possesses several features of ring main unit. It is the ideal equipment for urban network reconstruction. It features small volume, technological economy, high reliability, easy installation and free maintenance.
There are three compartments in the box. One compartment is sealed with micro-supercharged sulfur hexafluoride gas in it. There are more than one set of load switch whose operating mechanism is in the operation driving compartment. There are cable piles and terminals in the cable compartment, and the cable terminals are connected with load switch. The load switch in the compartment is rotary and moving-and-fixed-contacts-type load switch. The cables in the cable compartment are divided into one group every three phases. The sealed compartment has decompression channel.
