DFW8-12/24-630A 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&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 (cable connector), 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

Asia Electrical Power Equipment (Shenzhen) Co., Ltd. AEPE is a wholly-owned subsidiary in China by Asia Electrical Power International Group Inc - is a Nevada-headquartered American corporation, AEPE is a high-tech manufacturing company for power distribution switchgears, company established in 1994 currently experiencing solid revenues based on consistently increasing sales, through broader market penetration in the exploding electrical power industry sector centered in China.
The company combines manufacturing and trading with exporting and importing, electrical equipment/switchgear research & development. Since its inception AEPE has earned a distinguished position on the recommendation list of the State Economy and Trade Commission for national power distribution network construction in the People's Republic of China.
AEPE is an enterprise specializing in the manufacturing and marketing of complete high, medium and low voltage power distribution equipments/switchgears focused on the secondary power distribution industry (12-24-33KV). That industry has been experiencing substantial expansion in China because of the country's recent phenomenal economic vitality, allied to which the demand for electrical energy is extremely high and growing significantly. The company's principal products include cabinet-type substations, outdoor switching stations, cable branch stations and switching elements such as load break switches and circuit breakers.
During its early years AEPE cooperated with such world renowned high and medium voltage switchgear manufacturers as ABB of Switzerland and Schneider of France, both of whose products the company distributed in China.
In 1996, AEPE succeeded in developing the first medium voltage XGN15-12 (I) SF6 ring main unit switchgear in China, the core part of which is the ABB SF6 load break switch that optionally can be replaced by circuit breakers and insulating switches. Subsequently, AEPE completed R&D for the first medium voltage SF6 load break switch, FL(R)N-12D, and the first vacuum circuit breaker in China, the VDM6. Both of these products fully meet GB/IEC standards.
By combining high level technology with advanced equipment, diligent management, effective sales administration, quality controls and after-sales service, over the past decade AEPE has implemented an ISO9001-certified quality control system and attained industry recognition by being granted the Chinese National compulsive CCC certificate.
