Pipes
The electrical installation pipe is a product that facilitates the installation of electrical wires. It is used both in the case of the flush-mounted and surface-mounted method. This equipment is widely used in traditional housing construction. Laying wires or cables in an electrical installation pipe can even be considered a classic way to protect them. The unquestionable advantage of this type of casing is the possibility of replacing the wiring when it fails or when it needs to be replaced with newer materials. It also helps to keep the home electrical network tidy. The cables hidden in the pipe simply look more aesthetic - they do not get tangled, and this reduces the risk of making a mistake during renovation work. It should not be forgotten that this product protects the cables against mechanical damage. The only clear disadvantage of the electrical installation pipe is the fact that it takes a lot of time to perform the assembly using it and requires some practice. An electrical installation pipe can take various forms. Most often it is a cover with a round cross-section, although there are models with a different shape. Both insulated wires and electrical installation cables can be placed inside the product. However, it should be remembered that in one tube there should be wires forming only one circuit. Other solutions are prohibited for safety reasons - wires from more circuits in one sheath can even in the event of a minor failure lead to the destruction of the entire network. In the event of a defect, it is also more difficult to find an element that needs repair or replacement. Using such an installation is generally dangerous for users, because it is easier to create overvoltages, which in extreme situations can even lead to a house or apartment fire. Several types of electrical installation pipes are used in standard electrical installations. Threaded steel models are very common. They are used to cover wires in rubber or PVC insulation (without additional reinforcement protecting against mechanical damage). A steel electrical installation pipe works well wherever wires are extremely exposed to mechanical damage and should be protected in the best possible way (e.g. in factories, utility rooms). It is marked with the symbol RS-P11, RS-P29 etc. (the number means the diameter of the internal thread expressed in millimeters). In the case of slightly less demanding conditions, an electrical installation tube made of rigid, hard polyvinyl chloride is used. Although it is not as resistant to creases as a steel pipe, it protects the cables very well against high temperature, moisture and changing pressure. Importantly, the polyvinyl chloride pipe does not have threads. This means that it can be connected to another cable protected in this way by inserting the sheath into the so-called compensating coupling (possibly double-socket). This type of pipe is marked RVS 18, RVS 21 etc. It happens that the use of hard polyvinyl chloride is not possible. An alternative to this solution are products made of the same material, but subjected to additional processing, which gives them much greater flexibility. Such tubes are commonly called conduits. These products are ideal for flush mounting. They also work well in installations embedded in concrete. They can accommodate not only electric cables, but also telephone, water, sewage, central heating and fiber optic cables. The conduits themselves are divided into several types: reinforced, non-flammable, halogen-free (they do not emit harmful gases when burned), resistant to ultraviolet radiation and seamed (allowing to put the conduit on the existing cable without having to cut it). They are widely used due to such properties as: • easy maintenance, • easy modernization, • a wide range of available diameters (even up to 50 millimeters). Flexible electrical installation pipes made of polyvinyl chloride are marked with the symbol RVKL 15, RVKL 18, etc. When using them, it is recommended to pull a string, which may help in the subsequent laying of cables. It happens that some conduit models have a factory-installed internal cable to facilitate the subsequent placement of cables. It is recommended that such tubes do not form bends. It is best to arrange them in a straight line. If for some reason this is not possible, bends should have the smallest radius possible. For connecting, special slip-on connectors are used, which should be additionally wrapped with tape. This will strengthen the entire structure and reduce the risk of accidental separation of the two tubes. A specific type of electrical installation covers are the so-called heat shrink tubing. They are mainly used as a connector or cable insulation. Subjected to high temperature, they begin to tighten on the object on which they are placed, take its shape and thus create a very tight protective layer. There are several types of heat shrink tubing, including: thick, thin-walled, thick-walled, with glue and with mastic. In addition, there are electrical installation pipes made of RB plastics on the market. The offer of the EL12.pl store includes several types of electrical installation pipes. We offer models made of PVC, among which you can find products of various shapes and sizes. Among them there are covers in the form of elbows, straight connectors, compensating connectors and many others. A separate offer includes flexible PVC electrical installation pipes, which are more flexible, so they can be used in places where the use of stiffer models is impossible for various reasons. The vast majority of models have a corrugated structure, which increases the level of product protection. The great advantage of PVC pipes is their relative ease of welding and gluing. On EL12.pl you can also find threaded steel pipes. We also have accessories that facilitate the assembly and connection of various types of electrical installation pipes, e.g. aluminum handles, plastic handles, outlets for steel pipes, floor strips, nuts, connectors and many others. In addition to steel and PVC products, you can also find accessories made of ERP, HDPE, brass, PE, polyamide (also type PA6), polyethylene, polypropylene and thermoplastic. Electrical installation pipes from our offer come from reputable manufacturers. We have accessories of such brands as An-Kom, Arot Polska, Astat, EM Group, Elko-Bis, Elektro-Plast Opatówek, Elektroplast Stróża, Ergom, ZPTS Ingremio, Kopos, Lapp Kabel, Legrand, Marmat, Obo Bettermann, Ospel, Q- Systems, Tadpol, Tehalit and TTPlast. To facilitate the marking of wires and their circuits, we offer tubes in the following colors: white, blue, black, red, silver, grey, yellow, green and transparent.
