特点关键词∶阻燃防火、抗压、抗冲耐热、耐腐、绝缘、施工方便

1、阻燃防火。具有较高的氧指数值，故导管不易燃烧，且离火即自熄，火焰不会沿管道草延。

2、抗压。中型导管与重型导管分别能承受750N与1250N以上的压力，故可明装也可暗敷于混凝土内，不会受压破裂，其中重型管系列尤其适合暗敷在夯实和振动混凝土中。

3、抗冲耐热。导管在混凝土浇注过程中，能承受正常的捣固冲击而不破裂，且在混凝土凝结作业下，不会软化变形。

4、耐腐、防虫。PV导管耐酸碱性优良，不会锈蚀，且不含增塑剂，无吸引虫鼠的异味，故无虫害。

5、绝缘。在浸水状态下AC2000V、50Hz不会击穿，绝缘性能优良，故可有效防止意外漏、触电事故。

6、施工方便。导管截断方便，D32以下的导管内插入相应的专用弹簧，在常温下即可随意弯曲到所需要角度。用PVC粘合剂可便捷的把管道连接成施工所需的形状。

产品用途

应用于电力配管及室外通信电缆和光缆的管道系统。用于室内正常环境和在高温、多尘、有震动及有火灾危险的场所。也可在潮湿的场所使用。不得在特别潮湿，有酸、碱、盐腐蚀和有危险的场所使用。使用环境温度为-15℃～+40℃。

运输安装

1、使用穿线管埋线。

2、电路走线应该把握"两端间最近距离走线"，不能无故绕线，这样不但会造成死线，还会增大电改投入。

3、一根穿线管中不要穿太多线，穿线后都应该拽一下，看看是否可以轻松拽动。

4、线路有接头必需在接头处留暗盒扣面板，日后更换和维修都方便。

5、管径小于25的PVC穿线管拐弯应用弯管器，不能加弯头拐弯，直角死弯往往会造成死线。

6、管材剪切∶使用专用剪刀或自备钢锯将PVC电线管截成任意长度，切口应平整，可用剪刀背进行倒角。，

7、管材与管件连接∶连接前后注意保持粘接面清洁;在管材插入端外表面和管件承接口内表面均匀涂上胶粘剂，约一分钟后用力将管材插入管口内固定，不要随意扭转。

8、管材的弯曲∶用本厂提供相应规格弯管弹簧插入管内，便可进行弯曲。

PVC-U electrical casing

product description

The main raw material of PVC-U flame-retardant insulated electrical bushing is polychlorinated resin. Through the addition of various stabilizers, anti-aging agents, impact resistance agents, and other additives, threading pipes and pipes made by special extrusion and injection molding processes Pipe fittings. Mainly used for electrical and communication cable bushings. In layman's terms, it is a white hard PVC hose, a tube used for anti-corrosion, anti-leakage, and threading wires. The product is used in the electrical installation engineering of construction engineering to protect and protect the pipelines of wires and cables, and to allow the penetration and replacement of wires or cables.

Features

Feature keywords: flame retardant and fireproof, compression resistance, impact resistance and heat resistance, corrosion resistance, insulation, convenient construction

1. Flame retardant and fireproof. It has a high oxygen index value, so the duct is not easy to burn, and it will self-extinguish when leaving the fire, and the flame will not rush along the pipe.

2. Anti-stress. The medium-duty pipe and the heavy-duty pipe can withstand pressures above 750N and 1250N, respectively, so they can be exposed or concealed in concrete without breaking under pressure. Among them, the heavy-duty pipe series are especially suitable for concealed laying in compacted and vibrating concrete.

3. Impact resistance and heat resistance. During the concrete pouring process, the pipe can withstand the normal tamping impact without breaking, and it will not soften and deform under the concrete setting operation.

4. Corrosion-resistant and insect-proof. PV catheter has excellent acid and alkali resistance, will not rust, and does not contain plasticizers, and has no peculiar smell that attracts pests, so there is no pests.

5. Insulation. AC2000V, 50Hz will not break down under water immersion, and the insulation performance is excellent, so it can effectively prevent accidental leakage and electric shock accidents.

6. Convenient construction. The catheter is convenient to cut, and the corresponding special spring is inserted into the catheter below D32, and it can be bent to the required angle at normal temperature. With PVC adhesive, the pipeline can be easily connected into the shape required for construction.

Product advantages & details

PRODUCTSUPERIORITY&SHOWDETALS

High oxygen value, flame retardant and fireproof

PVC-U electrical casing has a high oxygen index value, so the pipe is not easy to burn, and will self-extinguish within 30 seconds from the fire, and the flame will not spread along the pipe.

Excellent heat resistance and insulation properties

Under water immersion, AC2000V, 50HZ will not break down within 15 minutes, and the insulation performance is excellent, so it can effectively prevent accidental leakage and electric shock accidents.

Resistant to impact and compression, not easy to deform

During the concrete pouring process, PVC-U electrical casing can withstand the normal tamping impact without breaking, and will not soften and deform under the concrete setting operation. Medium-duty pipes and heavy-duty pipes can withstand pressures above 750N and 1250N respectively, and can also be buried in concrete without breaking under pressure. Among them, the heavy-duty pipe series are especially suitable for concealed laying in compacted and vibrating concrete.

Anti-corrosion and insect-proof, convenient construction

Wanfang PVC catheter is excellent in acid and alkali resistance, will not rust, and does not contain plasticizers, and has no peculiar smell that attracts pests, so it is free of pests. The inner and outer walls of the pipe are smooth and bendable for easy threading. The pipe can be easily cut off, and the pipe can be easily connected to the shape required for construction with PVC adhesive.

Product Usage

It is used in power piping and pipeline systems for outdoor communication cables and optical cables. It is used in normal indoor environment and places with high temperature, dust, vibration and fire hazard. It can also be used in humid places. Don't use it in extremely humid, acid, alkali, salt corrosion and dangerous places. The working environment temperature is -15℃～+40℃.

Transport and installation

1. Use threading pipe to embed the thread.

2. The wiring of the circuit should be based on "the shortest distance between the two ends of the wiring", and cannot be wound without any reason. This will not only cause dead lines, but also increase the investment in power reforms.

3. Don't thread too much thread in a threading tube. You should pull it after threading to see if it can be pulled easily.

4. If the line has a connector, it is necessary to leave a cassette buckle panel at the connector, which is convenient for future replacement and maintenance.

5. The bending of PVC threaded pipes with a pipe diameter of less than 25 should use a pipe bender, and no elbow can be added.

6. Pipe cutting: Use special scissors or self-prepared hacksaw to cut the PVC electric wire pipe to any length. The cut should be flat and the back of the scissors can be used for chamfering. ,

7. Connecting pipes and pipe fittings: Keep the bonding surface clean before and after connection; apply adhesive evenly on the outer surface of the pipe inserting end and the inner surface of the pipe fitting socket. After about one minute, insert the pipe into the pipe mouth and fix it, do not twist at will.

8. Bending of the pipe: Insert the corresponding specifications of the elbow spring provided by our factory into the pipe, and then it can be bent.
