在工程施工过程当中,经常运用到电缆维护管,可是关于电缆维护管的详细影响,各人能否分明呢?下面康美塑化为您引见电缆维护管是什么及电缆维护管的影响。
In the process of construction, it is often applied to the cable maintenance pipe, but the detailed impact on the cable maintenance tube, each can clearly? The above business treasure for you to introduce what the cable maintenance tube and cable maintenance tube influence.

电缆维护管别名电缆管、电力电缆管、水泥电缆管、电力排管、电力电缆维护管等。电缆维护管次要装置在通信电缆与电力线穿插的地段,避免电力线发作断线形成短路变乱,惹起通信电缆和钢丝绳带电,以维护电缆、交换机、机芯板,以致零件不被烧坏,对电力线磁场搅扰也起到必然的断绝影响。
The cable maintenance pipe is named as cable pipe, power cable pipe, cement cable pipe, power line pipe, power cable maintenance pipe and so on. Cable maintenance device inserted in the secondary communication cable and power line area, avoid power line disconnection attack forms a short circuit accident, cause communication cable and wire rope charged, in order to maintain cables, switches, circuit board, so that parts will not be burnt, also to sever impact of inevitable to the power line magnetic field interference.
同时运用涂塑电缆维护套管维护电缆能够到达以下劣势:
At the same time the use of plastic cable maintenance maintenance cable can reach the following disadvantages of casing:
1、良好的耐腐蚀,运用寿命长,可在湿润盐碱地带运用。
1, good corrosion resistance, long service life, can be used in saline and alkaline areas.
2、电缆维护管载流量高、热阻系数低。
2 、 high ampacity of cable maintenance and low thermal resistance coefficient.
3、阻燃、耐热性好,可在130度低温下临时运用而不变形,遇火不燃烧。
3, flame retardant, heat resistance is good, can be used at 130 degrees low temperature temporary use without deion, fire is not burning.
4、电缆维护管运用时,与电缆间的磨擦系数低,电缆穿过期更便利。
4, the use of cable maintenance tube, and between the cable friction coefficient is low, cable wear more convenient.
5、强度高、刚度高。用在行车道下直埋无需加混凝土维护层,能辊快电缆工程建设进度。
5, high strength, high stiffness. The utility model is directly buried under the driving way without adding a concrete maintenance layer, and can speed up the construction progress of the cable project.
6、电缆维护管加长了井距,减低了工井数目,降低了工程本钱 。
6 、 the cable maintenance Pipe lengthens the well spacing, reduces the number of working wells and reduces the cost of the project.
7、涂塑电缆维护套管无论是管材仍是管件都具有必然柔性,能抵挡外界重压和根底沉降所惹起的毁坏。
7, plastic cable maintenance casing for pipe fittings are still has certain flexibility, can resist the external stress and foundation settlement caused by the destruction of.
8、具有良好的抗外界旌旗灯号搅扰功能。
8, with good anti signal interference function.
9、内壁光滑,不刮伤电缆。设想接纳承插式的衔接方法,便利装置衔接。讨论处加橡胶密封圈封既顺应热胀冷缩,又避免泥砂进入。
9, smooth inner wall, no scratches on the cable. The idea is to accept the plug in connection method and facilitate the device connection. Rubber seals are added at the discussion site to conform to both thermal expansion and cold shrinkage and to prevent mud penetration.
