To install conduit correctly, M&amp;E M&amp;E engineers need to understand 35\u00a0regulations on installation of electrical conduit\u00a0According to\u00a0Section 8 of TCVN 9208:2012 standard for industrial works as follows:<\/p>\n<p>1. A rigid metal conduit system must be applied. To be able to protect cables in the production area, supplement the cable tray system.<\/p>\n<p>2. The conduit system is fully installed before the cable is inserted into the conduit. For this purpose, in the conduit, a primer must be available to pull the cable into the conduit. This standard is not mandatory for conduit systems placed in precast concrete structures.<\/p>\n<p>3. For conduit systems in precast concrete structures. Wires and cables can be pre-threaded before concrete is poured. But measures must be taken to protect the end of the pipe to prevent mortar or concrete from entering the pipe. At the same time protect the wire ends sticking out of the pipe mouth from being broken.<\/p>\n<p>4. For conduit systems in precast concrete structures. Pipes or cables should not be subjected to mechanical stress arising during installation and placing of concrete.<\/p>\n<p>5. Before pouring concrete over conduit, these pipes need to be fixed. So that\u00a0thickness of concrete\u00a0after setting\u00a0encloses the conduit cross section. At any point\u00a0not less than 15 mm.<\/p>\n<p>6. Total cross-section of cables or wires in conduits placed in concrete. Do not exceed 40% of the cross-section of the conduit.<\/p>\n<p>7. Rigid conduit gland must be firmly fixed with clamps or other approved method. After the distance is not more than 2 m for metal conduit. And no larger than 1 m with rigid PVC conduit.<\/p>\n<p>8. Steel conduit and accessories if placed in a humid, corrosive atmosphere. It must be hot galvanized or painted with anti-rust and anti-corrosion materials.<\/p>\n<p>9.\u00a0Steel conduit for conduit\u00a0continuous length must have threads at both ends of the pipe mouth.<\/p>\n<p>10. Open pipe mouth must be equipped with a bushing or a flared pipe. In order not to damage the cable insulation. If the open end of the pipe is inside the cover trough. Then use the bushing, and if the open end protrudes, use the flared mouthpiece.<\/p>\n<p>11.\u00a0The number of conduit elbows on a conduit is limited. Such that the total number of angles in all pipe bends\u00a0doesn&#8217;t exceed 4\u00a0right angles. When encountering obstacles, the radius of curvature of the pipe elbow can be widened to facilitate installation. The angle of the conduit elbow is not less than 90\u00b0. When bending pipes, do not reduce the inner diameter of the pipe.<\/p>\n<p>12. Conduit of medium-voltage cables is easy to identify thanks to contrasting colors and warning signs.<\/p>\n<p>13. Metal conduit ensures electrical continuity. Metal conduit must be grounded and connected to the nearest ground wire.<\/p>\n<p>14. When installing pipes, it is necessary to take measures to prevent water ingress.<\/p>\n<figure id=\"attachment_2453\" aria-describedby=\"caption-attachment-2453\" style=\"width: 480px\" class=\"wp-caption aligncenter\"><img loading=\"lazy\" decoding=\"async\" class=\"wp-image-2453 size-full\" title=\"Quy \u0111\u1ecbnh l\u1eafp \u0111\u1eb7t \u1ed1ng lu\u1ed3n d\u00e2y \u0111i\u1ec7n\" src=\"https:\/\/mcw663.com\/wp-content\/uploads\/2022\/06\/bang-gia-ong-thep-luon-day-dien.jpg\" alt=\"Quy \u0111\u1ecbnh l\u1eafp \u0111\u1eb7t \u1ed1ng lu\u1ed3n d\u00e2y \u0111i\u1ec7n\" width=\"480\" height=\"360\" srcset=\"https:\/\/mcw663.com\/wp-content\/uploads\/2022\/06\/bang-gia-ong-thep-luon-day-dien.jpg 480w, https:\/\/mcw663.com\/wp-content\/uploads\/2022\/06\/bang-gia-ong-thep-luon-day-dien-300x225.jpg 300w\" sizes=\"auto, (max-width: 480px) 100vw, 480px\" \/><figcaption id=\"caption-attachment-2453\" class=\"wp-caption-text\"><em>Regulations on installation of electrical conduit<\/em><\/figcaption><\/figure>\n<p>15. Before threading the cable, the inside of the conduit must be cleaned thoroughly. Primer wire must be used to pull the cable inside the tube. However, do not use grease or lubricating material when pulling the cable through the conduit. As this may damage the cable insulation.<\/p>\n<p>16. On long pipelines at the narrowing stage, thermal expansion must be compensated by expansion joints.<\/p>\n<p>17. When placing the conduit route, it is necessary to choose the location of the junction box and accessories for convenient access to repair.<\/p>\n<p>18.\u00a0Use only conduit\u00a0and accessories\u00a0with protective non-combustible materials:<\/p>\n<p>\u2013 Power cable for alarm, fire fighting equipment, human evacuation equipment and elevators.<\/p>\n<p>\u2013 Cables placed in flammable areas.<\/p>\n<p>19. Pipes and electrical cables into the equipment are arranged with anti-liquid gaskets according to the pipes entering the equipment.<\/p>\n<p>20. The gaskets of pipe fittings shall be resistant to the corrosive effects of the material in contact with them.<\/p>\n<p>21. Plastic conduits for electrical conduit are placed in an area where there is no corrosive effect. May be rigid pipes with threadless fittings.<\/p>\n<p>22. Polyethylene conduit recessed in brick or plaster walls in offices or similar areas. It shall be fixed so that the outside surface of the pipe is at least 15 mm deeper than the finished wall.<\/p>\n<p>23. Threaded metal conduit joints have washers of conductive material with anti-corrosion effect. And there must be no harm to the insulation of the cable.<\/p>\n<p>24. Outdoor conduit is PVC conduit for conduit or &#8216;tropicalized&#8217; steel conduit.<\/p>\n<p>25. The rigid conduit shall have a radius of curvature (corresponding to the inner bend) large enough for the cable in the conduit to be bent as specified in the table below, but in no case less than 2.5 times the outside diameter of the conduit. tube.<\/p>\n<table dir=\"ltr\" style=\"width: 96.4781%;

The mouth of the short pipe that penetrates the wall leading the cable into the house must be sealed with a material that is not combustible and does not damage the insulation of the cable.<\/p>\n<p>29.

Do not use wood to fix the conduit and only use electric drills or pneumatic drills to drill holes for fixing wires.<\/p>\n<p>33. Construction of the pipeline can only be started when the location of the pipeline can be determined based on the drawing of the design consultancy agency.<\/p>\n<p>34. When cutting conduit, it is necessary to cut it at right angles to the axis of the conduit.<\/p>\n<p>35.
