产品简介

江苏春晨电缆有限公司生产YCB扁电缆卷筒电缆,用于起重机,行车,吊车,适用于频繁移动,移动式配电箱格式与固定式配电箱相同，用橡套软电缆接在固定分配电箱上，移动到尽量接近用电设备处，比如从楼下引至楼上施工层

详细介绍

江苏春晨电缆有限公司生产YCB扁电缆卷筒电缆,用于起重机,行车,吊车,适用于频繁移动,

固定分配电箱：

Fixed distribution box:

由于施工现场线路敷设多用电缆线路直埋敷设，供电系统采用放射式，每个固定式配电箱就是这条支路的终点，因此一般放置在本支路用电设备附近。

Due to the multi-purpose cable laying on the construction site, the direct buried laying of the line, the radial power supply system, each fixed distribution box is the end of this branch, so it is generally placed near the electrical equipment of this branch.

。总开关后面装几只分路开关，也用四极漏电开关，容量按常用电器规格大小组合。比如总开关用200A漏电开关，设四个分路，两路60A，两路40A。分路开关下口要加装瓷插式熔断器作为明显断开点，并做为设备接线端子，熔断器上口接漏电开关下口，下口空着准备设备接线用。必要时，箱内要装单相开关，准备接单相设备使用。YCB扁电缆卷筒电缆

The shell of the fixed distribution box is made of thin steel plate, and the top is rainproof. The height of the box from the ground is more than 0.6m, and the angle steel is used as the leg support. The box is open on both sides, and the insulating board is used as the electrical installation base plate. A 200 ~ 250A main switch and a four pole leakage switch are installed in the box, and the capacity is the maximum rated current of the electrical appliances. Considering the universality, it can be used according to the requirements of various equipment used on the site For example, each box can be connected to tower crane or electric welding machine. Several shunt switches are installed behind the main switch, and four pole leakage switch is also used. The capacity is combined according to the specifications of common electrical appliances. For example, the main switch uses 200A leakage switch, with four branches, two 60A and two 40A. The lower port of shunt switch shall be equipped with porcelain plug-in fuse as obvious disconnection point and used as equipment wiring terminal. The upper port of fuse shall be connected with the lower port of leakage switch, and the lower port shall be empty for equipment wiring. If necessary, the box should be equipped with single-phase switch, ready to use single-phase equipment.
