KDF Serial Switch Branch Box

The switching cable branching box is characterized by full insulation, full seal, anti-corrosion, maintenance-free, safety, reliability, small size, compact structure, simple and convenient installation, flexibility, etc., due to these, it is widely used in the electric power system. As for the switch, the TPS serial switch with visible isolated break is imported from Italy. For the switch, the SF6 gas which is advanced in arc extinguishing performance is adopted as insulation and arc extinguishing medium. Its good insulation, very short arcing time, window making the isolated break visible and stainless steel enclosure that is corrosionproof, present the best performances of the cable branching box, and meet fully the requirements of the electric power users_that the distribution automatic equipment should be fully insulated, fully sealed, highly reliable, free from oil, multi-combined, free from maintenance, modular, corrosion-proof, etc.

A load switch or vacuum circuit breaker is equipped to each ring main unit line of the KDF serial products. Any branch loop can be put into operation and exit from operation freely without affecting other ring main unit loops. Fuse can also be installed in the load switch. When a branch loop is in short trouble, the fuse of it can break the faulted loop quickly, and impact the trip of the load switch for breaking, like this, the faulted loop is separated, which ensures the continuity of power supply of the non-faulted loops. The KDF serial switch branch box has not only the load separation function of the ring main unit, but also the multi-branch feature of the branch box, and its price is much lower than the fabrication cost of the ring main unit. So it is widely used by users in urban industrial communities, residential districts, business zones, business centers, mine fields, airports, railways, wind-power stations, switching stations, distribution networks of steel, petroleum, chemical industry, cement enterprises and other large-scale enterprises. Especially it is suitable to be used for the electric network transformation project of the urban roads, can cut a lot from the investment for electric equipment and cables, and raise the reliability of power supply.

For the switching cable branch box, mainly single switch or multiple switches are adopted. As for its switch, load switch, circuit breaker, load switch + fuse combination may be adopted. For its cable fittings, American type or European type structure may be adopted, with full insulation and full seal. As for the incoming and outgoing line loops, these types like one incoming and one outgoing, one incoming and two outgoing, one incoming and three outgoing, two incoming and one outgoing, two incoming and two outgoing, two incoming and three outgoing, etc. May be adopted according to the use requirements. The switching cable branch box, with multi-cable branches, separates switching operation from incoming and outgoing lines, and it is uniquely featured by good look, convenient operation, safety, reliability, etc. Its switch can be operated manually or can operate itself automatically, and for its circuit breaker for protection, the domestically manufactured or imported integrated relay protection device is adopted.
