DFW-12型户外高压电缆分接箱
DFW-12 type, high-voltage cable connects box for outdoor installation
性能与用途
DFW-12型户外高压电缆分接箱适用于12kV,50Hz三相交流电缆配电网络，是电缆续接和分接的配电设备。
本产品外壳采用不锈钢板制造，有足够的机械强度；具有耐腐蚀性能，表面抛光或静电喷涂。小巧、美观、安装方便、基础量小，可灵活分接400mm2及以下的电缆，2~10分支任意组合。箱内装有可从外部观察的带电显示装置，便于用户维护时确认。一次回路采用全密封硅橡胶复合绝缘，保证在凝露和覆冰时不会影响绝缘，并具有防洪能力，是理想的电缆分接设备。
Functions and Applications
DFW-12 type high-voltage cable connection box for outdoor installation can be used in 12kV, 50Hz, 3-phase AC cable distribution network to function as cable linking and distribution devices.
The box is made of stainless steel sheet with sufficient mechanical strength and corrosion-resistant function. The appearance is well polished or electrostatic painted. It is characterized by its slim size, good appearance, convenient installation, low basic requirements, freely connection with cables of size small than 400mm2 and combination of 2-10 branches. The load display device observable from outside is installed in the box so that the users can confirm easily in the maintenance. Silicon and rubber complete insulation is used in main circuit so as to remove the influence to the insulation function under the dew and icy weather and the worst, the flood. This is indeed an ideal cable connection device.
