  一、家装电线暗套的电子管需要,需要根据不同的需要进行选择,无论是PVC、镀锌管还是铁管,都需要根据需要选择。

  1、 The need of the electronic tube of the concealed sleeve of the home electric wire needs to be selected according to different needs, whether it is PVC, galvanized pipe or iron pipe, it needs to be selected according to the needs.

  二、现在国内的安装电路都是采用暗埋的方式,电线产品本身的保护层不足以保护内部的芯线,常见的做法是将电线套在管中放入电槽中。因此,电路改造还需要准备螺纹管等配套保护材料,以便在安装时使用。

  2、 At present, the installation circuit in our country is buried in a concealed way. The protective layer of the wire product itself is not enough to protect the internal core wire. The common way is to put the wire in the pipe and put it into the electric slot. Therefore, the circuit transformation also needs to prepare threaded pipe and other supporting protective materials for use in installation.

  三、电线不能直接敷设在墙壁上,必须用电线保护管进行保护,除便于维修外。根据性能、不同场合的使用,等等,家中经常使用的螺纹管有以下几个:

  3、 The wire cannot be laid directly on the wall. It must be protected with wire protection tube, except for the convenience of maintenance. According to the performance, use in different occasions, and so on, there are several screwed pipes that are often used at home:

  1,塑料螺纹管塑料螺纹管,因为价格便宜,施工方便,不会生锈等优点,使用更常见的在家里电路转换。其中常用的塑料管是PVC管,其主要成分是聚氯乙烯,除了添加其他成分以增强其耐热性、韧性、延展性等。在选择PVC螺纹管时,要对管的质量进行检查,确保保护管在受到冲击后不会弯曲变平或开裂。首先检查管道外壁是否有出厂标志和阻燃标志。此外,管道可以先被火点燃,然后从火源处疏散,看它是否会在30秒内自行熄灭;第三,可以试着将管子弯曲90度,看弯曲后的外观是否光滑;四、锤击可使管子变形,无裂纹,冲击试验合格。

  1. Plastic threaded pipe plastic threaded pipe, because of the advantages of cheap price, convenient construction and no rust, uses more common circuit conversion at home. The common plastic pipe is PVC pipe, its main component is PVC, in addition to adding other components to enhance its heat resistance, toughness, ductility and so on. When selecting PVC threaded pipe, check the quality of the pipe to ensure that the protective pipe will not bend, flatten or crack after being impacted. First, check whether there are factory signs and flame retardant signs on the outer wall of the pipeline. In addition, the pipe can be ignited by fire first, and then evacuated from the fire source to see whether it will extinguish itself within 30 seconds; thirdly, try to bend the pipe 90 degrees to see whether the appearance after bending is smooth; fourthly, hammer can make the pipe deformed without cracks, so the impact test is qualified.

  2、金属丝管(铁管、镀锌钢管)在家用除阻燃塑料管套保护丝外,还可用于保护金属丝管(金属丝管)。如有的住宅建筑电源线采用阻燃塑料管保护,而电话、有线电视采用镀锌金属薄壁管(可起到屏蔽作用)。在电话和有线电视传输线的金属保护管中不需要安装跳线,因为镀锌管通过电线口或套管连接可以满足屏蔽要求。普通金属管为镀锌钢管,耐热、耐火。金属丝管、镀锌丝管只适用于高层建筑,虽然造价较高,但不易弯曲变形。在选择金属管道时,注意管不应平坦了,不应该有毛刺在管,钢管的外径和壁厚应符合相关的国家标准,如果钢管出现腐烂的牙齿或钢管出现脆性断裂现象,这表明钢管的质量不符合要求。

  2. Metal wire pipe (iron pipe, galvanized steel pipe) can be used for protecting metal wire pipe (metal wire pipe) in addition to flame-retardant plastic pipe sleeve protection wire at home. For example, the power line of some residential buildings is protected by fire-retardant plastic pipe, while the telephone and cable TV are protected by galvanized metal thin-walled pipe (which can play a shielding role). Jumpers are not required in the metal protective tubes of telephone and cable TV transmission lines, because the galvanized tube can meet the shielding requirements through wire port or sleeve connection. Common metal pipe is galvanized steel pipe, heat-resistant and fire-resistant. Metal wire pipe and galvanized wire pipe are only suitable for high-rise buildings. Although they are expensive, they are not easy to bend and deform. When selecting metal pipes, pay attention that the pipes should not be flat, there should be no burr in the pipes, the outer diameter and wall thickness of the steel pipes should meet the relevant national standards. If the steel pipes have rotten teeth or brittle fracture, it indicates that the quality of the steel pipes does not meet the requirements.
