Electrical Installation Rules (PUE) prescribe in some cases to be used when laying electrical wiring flexible corrugated pipes … In the past, heavy metal varieties of these products were used, but they are hardly used today. The undisputed leaders these days are lightweight, inexpensive and non-conductive corrugated plastic pipes. A large assortment of these products is offered by the Russian plant EKOPLAST.
The use of plastic corrugated pipe for electrical wiring allows you to solve three tasks at once: • to protect cable lines from the adverse effects of atmospheric factors; • significantly reduce the likelihood of ignition of cables by limiting the supply of oxygen to them, which supports combustion; • finally, to protect the insulation and other parts of the cables from damage that could arise from mechanical stress.
In order for all the listed tasks to be successfully solved, it is important to choose the right material. corrugations for wires taking into account the conditions of its operation. The most popular are PVC (polyvinyl chloride) and HDPE (low pressure polyethylene) pipes manufactured by the EKOPLAST plant. Each of the listed materials is appropriate in its own case.
PVC corrugated pipes
These products are manufactured from a self-extinguishing PVC compound, they meet regulatory requirements in the field of fire safety, which significantly expands the scope of its application. The assortment includes: • light pipes (FL series), designed for open and hidden wiring on walls, ceilings and floors; • heavy pipes (FH series) with increased strength and pressure resistance. These varieties allow for laying in concrete or cement screed, operation in other similar conditions in which they will be loaded. Summarizing the characteristics corrugated pipe for electrical wiringmade of PVC, we can conclude: they are optimal for indoor use.
HDPE corrugated pipes
These varieties are made of low-pressure polyethylene, low-combustible, an environmentally friendly material that allows operation in a wide range of environmental conditions. They can be operated at ambient temperatures from -25 to + 90 ° C, are not afraid of the effects of oils and gasoline, they are able to withstand higher (BH series) or lower (BL series) pressure. Generalization of the characteristics of corrugated pipes made of HDPE allows us to conclude that they are optimal for use in the open air - for example, for laying along the outer walls of buildings.
Several reasons to choose corrugated pipes of the EKOPLAST plant
Both HDPE and PVC pipes have significant fire safety restrictions. Therefore, the EKOPLAST assortment includes corrugations and rigid pipes made of halogen-free compositions (HF, HFR), as well as certified E90 pipes and accessories for building OCL (fire-resistant cable line). EKOPLAST products are manufactured using modern technologies from high quality plastic. It has successfully passed certification in accordance with the industry standards of Gosstandart and Rospotrebnadzor of the Russian Federation, and has an EC certificate. This allows us to guarantee reliable protection of cable lines and a long service life of pipes - of course, subject to the rules for their installation and operation.
A wide range of corrugated pipesmade of different materials and having different characteristics - larger and smaller diameters, designed for higher and lower loads, equipped with a wire probe for pulling the cable and without a probe - allows each customer, without overpaying, to buy pipes that are best suited for his case.
Corrugated pipes for electrical wiringproduced by the EKOPLAST plant are the best choice.
