630A European-Style Ordinary High-Voltage Outdoor Cable Branch Box Medium Voltage Products
DFW series cable branch box is outdoor design, fully sealed structure, the protection class of the cabinet can reach IP33.
The cable joint bracket is made of stainless steel, and the external form is made of 2mm high-quality stainless steel plate. The inner part of the box is divided into bus room and cable bin by the cable warehouse roof. The bus room is a sealed room enclosed by 2mm steel plate. The cable joint bracket is located at the upper part of the bus room to support the bushing, which is used to fix the cable joint. The interphase distance of the cable joint is 180mm.
For the arrester type, the arrester is installed at the end of the cable connector. In addition, the short circuit indicator and live display are also installed in the bus room. All live parts of bus room are treated with strict silicone rubber insulation.
The cable warehouse is located in the lower part of the bus room, which is the channel for cable entry and exit. There are cable fixing clamps and grounding terminals in the warehouse.

Product Description:
High voltage cable branch box is widely used in electric power distribution system of cabling engineering equipment, its main characteristics are two-way door, the use of wall bushing as connection bus, with small volume, clear cable arrangement, three core cables do not need large span crossing and other significant advantages.
Comprehensive technical features of 35kV cable tap box:
1. Inner cone plug and pull type structure, full insulation, full sealing, full protection structure design, outdoor maintenance free operation. Resistant to heavy pollution, condensation, frost, water immersion, and not limited by altitude.
2. The flexible combination of flexible silicone rubber insulation and aluminum alloy shielding shell can realize the main body of 2~4 branches of the tap box a shielding joint body (fully insulated bus), with high strength mechanical characteristics and reliable grounding protection characteristics.
3. Flexible connection and branching of cables of different materials and specifications can be realized.
4. Separate phase independent inner cone plug and plug connection, easy to quickly fold and replace the cable, can be separately for the main body of the tap box and each cable related test. Search and troubleshoot.
Equipped with electric indicator, lightning arrester and short circuit fault indicator can be added.
SF6 load switch for 35kV cable tap box main technical characteristics:
1. The inlet and outlet side of the switch adopts the inner cone connection mode, so that the cable and the switch are fully sealed.
2. Load switch adopts pneumatic internal blowing structure, arc extinguishing ability is strong, and does not affect phase and ground insulation, dynamic and static contact with arc contact, greatly improve the number of breaking.
3. The operating mechanism is located in the front of the switch, and the load switch is equipped with spring energy storage or electric operation mechanism. The operation of the load switch and the connection switch is equipped with bismuth device to prevent wrong operation.
