| ADF-630 type series cable branch cabinet, an outdoor high-voltage electrical equipment with the rated voltage of 12kV and the rated current of 630A, can be used for the cable connection and branching connection the method of which is simple?flexible?safe and reliable. The cabinet crust is made of 2 millimeters of stainless steel plate which is strong and durable. Charged parts are structured with complete insulation and seal. By the adoption of touchable flood-proof cable head, flood-resistance can be realized to greatly advance the power supply reliability. This product is widely used in city industrial districts, residential districts, business centers, mining areas, airports, railroads, wind power station, switching substations and large-scale enterprises like iron, petrol, chemistry, cement industries etc. as well as other distribution net especially for the reform project of electric network of city road.
The product is in conformity with the standards of GB3804-90, GB311.1-97, GB11033.2-89, GB4028-93, GB11032-2000. |
