PVC pipes
PVC or polyvinyl chloride - a polymer with excellent performance properties and dielectric properties. Thanks to this, PVC pipes have found wide application in gasket electrical communications.
Kinds
The main purpose of electrical PVC pipes is to protect cables and wires from mechanical damage, fire.
PVC pipes are presented in several modifications:
- flexible and tough;
- with and without a broach;
Most electricians prefer to use electrical corrugated PVC pipes with a probe. Such constructions provide ease of installation of power and low-current lines.
Specifications
Features of PVC pipes:
- Working temperature range - from -5C ° to + 65C °.
- Excellent dielectric. In case of damage or rupture, as well as short short-circuiting the cable PVC pipes can protect people from accidental injury electric shock.
- Resistance to ignition. Exposed to high temperatures PVC does not spread fire.
- PVC is resistant to corrosion, therefore pipes made of PVC can be used for wiring in rooms with increased humidity: warehouses, industrial premises.
- Strength. Light series pipes are mainly used for installation inside buildings, in an open (along walls, ceiling) way. Heavy series corrugated pipes are distinguished by a large margin of safety, for example, they can Use when pouring into concrete screed.
The disadvantages of products include low frost resistance. At temperatures below -15 ° C, the material becomes brittle, loses its operational properties.
Features of choice
When choosing pipes made of polyvinyl chloride, one should take into account the scope of their application and possible mechanical stress. For hidden wiring, it is better to choose corrugated pipes. If it is placed in a floor screed up to 15 cm thick, then you can buy light PVC. Heavy series pipes withstand a significant load equivalent to a concrete screed up to 40 cm thick.In projects where small lines are laid more often use light corrugations with a diameter of 16 to 32 mm with a broach:
- for power supply of switches - 20 mm;
- for power outlets - 20mm;
- for lighting devices - 16 mm;
- when connecting a telephone or internet cable - from 16 mm;
- when connecting shields and junction boxes - 25 mm;
- to ensure interfloor connections - 40 mm.
Purchase pipes of a suitable design and diameter on the website manufacturer "Ecoplast". Also available for ordering accessories for highways from polyvinyl chloride pipes: adapters, couplings, tees.
