电缆桥架配件知识讲述

电缆桥架适合用于工矿企业室内外架空敷设电力电缆、控制电缆,也用于电信、广播电视等部门的室内外架设。
The cable tray is suitable for laying power cable and control cable indoors and outdoors in industrial and mining enterprises, and also for indoor and outdoor erection in telecommunication, radio and television departments.
为了规范电缆桥架配件和电缆桥架市场,相关部门公布了桥架配件的标准定义。电缆桥架厂家提醒诸位,电缆桥架的购买也是极其重要的,配件的选择需要优质、抗压,能满足施工需要。常用的电缆桥架有三通、弯头、异径、螺丝、扣锁、托臂、吊杆、横担、连接片、接地线等等。
In order to standardize the cable tray accessories and cable tray Market, relevant departments published the standard definition of cable tray accessories. Cable tray manufacturers remind you that the purchase of cable tray is also extremely important. The selection of accessories needs high quality and compression resistance to meet the construction needs. The commonly used cable trays include tee, elbow, reducer, screw, lock, bracket, suspender, cross arm, connecting piece, grounding wire, etc.
常用的桥架附件有电缆终端接线盒、电缆中间接线盒、连接管及接线端子、钢板接线槽等等。对于振动场所,在接地部位的连接处应装置弹簧圈。桥架系统应具有可靠的电气连接并接地。当允许利用桥架系统构成接地干线回路时应符合一下要求:
Common bridge accessories include cable terminal box, cable intermediate box, connecting pipe and terminal, steel plate wiring slot, etc. For vibration place, spring coil should be installed at the connection of grounding part. The bridge system shall have reliable electrical connection and grounding. The following requirements shall be met when the main line grounding system is formed:
1桥架端部之间连接电阻不能大于0.00033欧姆,接地孔应清除绝缘涂层。
1. The connection resistance between bridge ends shall not be greater than 0.00033 ohm, and the insulation coating shall be removed from the grounding hole.
2在1kv及以下中性点直接接地系统中,受电设备的接地与系统中性线接地相连。
2. In the system of 1kV and below neutral point direct grounding, the grounding of the receiving equipment is connected with the neutral line of the system.
