Cables protector and circulation can be done in the following ways:

The cables must not be directly embedded in the walls.

Protection against external risks must be provided throughout the continuity of the circulation of electrical networks.

In the buried installation, only electric cables are allowed.

The trunking installed in plinths must have an index.

The Different Mechanical Protections For Electric Wires And Cables

To meet the requirements of the standard in terms of cables and wires, it is possible to install different electrical equipment, the best known of which are:

The Electric Trunking And Molding

The electric molding and the chute are two material means used in the so-called apparent installation method. The electrical networks circulate in a plastic base closed by a plastic cover.

Electric trunking and moldings have a degree of mechanical protection that allows them to adapt to the environment in which they are installed. The index varies by brand and model.

Note:

The main difference between the term chute and molding is in size and use. The molding is used domestically to bring the electric wires to the equipment (sockets, switches). The trunking is used in tertiary electricity to direct bundles of high current or weak current electrical networks.

The IRL tube:

The IRL tube is used for surface mounting. It is most often used in areas where aesthetics do not take precedence (garage, cellar, attic, etc.) The IRL tube, also used in surface-mounted electrical assemblies, provides mechanical protection.

This protection is valid in tubes. Without accessories (such as 90 ° elbows), the protection is no longer valid.

The ICTA sheath:

The so-called ICTA sheath (for Transversally Elastic Ringed Bendable Insulation) is probably the element most used for the circulation of electrical networks in a domestic electrical installation.

The scabbard says TPC:

The so-called TPC sheath is used in an underground electrical sheath, such as an EDF sheath, underground electrical sheath, and mechanical protection index. This sheath is subjected more than the others to the risk of mechanical shocks (in particular during the filling phase of the trench).
