ELECTRICAL INSTALLATION SYSTEMS

In our country, spiral or flat PVC pipes are commonly used for cable pulling during electrical installations. Especially in industrial facilities, water pipes are generally used as metal installation pipes by replacing them.
Nowadays, flat metal pipes used internally and externally in electrical installations in social and industrial facilities, business centers, workshops, skyscrapers, subway stations, ships are divided into two groups as threaded and toothless types.
While toothless pipes are mainly made of galvanized steel; They are made of threaded pipes, aluminum or steel. The most commonly used steel pipes in the world are EMT (Electrical Metallic Tubing) type pipes.

WHAT IS EMT?

EMT installation systems are manufactured according to American UL 797 and ANSI C80.3 standards and are recognized by NEC (National Electric Code). EMT is not only pipes, but also muffs, fittings, junction boxes, channels, fixing hooks, clamps, elbows, bushings, adapters, entules and bending apparatus, etc. It is a complete electrical installation system consisting of accessories. The application of EMT installation materials is a more practical, easy and at the same time safer method of application compared to other piping systems.

WHAT IS EMT PIPE?

EMT pipes are galvanized steel pipes without teeth used in electrical installations. They are used for safe and easy pulling of cables during electrical installation. They are suitable for use in indoor and outdoor environments.
It is difficult to provide strong protection because the environments where the cables are placed are often poor. Thanks to the galvanized coating process, it is a good solution for corrosion protection. Calcification, rusting, etc. that occur over time in the electrical installation with EMT pipes. It provides strong protection against electrical, chemical or mechanical abrasion. With this feature, EMT pipe provides the protection of cables and wires for a long time.
In EMT piping, pipe connections are made with the help of screw or compression fittings and muffs without the need for threading. With this feature, EMT pipes eliminate the need for threading, which is encountered in threaded pipes, which requires both special equipment and increases the labor cost in the field. EMT Piping is an alternative, durable solution to plastic-based pipes, especially in surface mounted installations.

Where to Use Steel Spiral Pipe

We strongly recommend the use of steel spiral hoses in various construction sites, especially shaft gaps (ventilation, elevator shafts, etc.).

The usage areas of spiral pipes and steel spiral pipes are different. Steel spiral pipes are used for cables in areas that may be exposed to loads and impacts. This is because it prevents the steel spiral pipes and cables from being damaged and damaged. The steel spiral pipe is not crushed or damaged.

In places where the cable cannot be fixed, steel spiral pipes should be used. Rodents are likely to be found in shaft cavities in construction areas. Rodents gnaw through electrical cables, causing extensive damage to the cables. To prevent this, it is necessary to use spiral pipes.

Spiral Pipe Production

A sheet of the diameter of the steel spiral hose to be produced is wrapped in a circular shape inside the machine and the bending machine and the clamps are clamped together. The intertwining of the clamps is related to the internal and external bending during the production phase.
For the production of PVC coated steel spiral pipes, after the spiral hose production is completed, PVC coating is made by the extruder machine.
After the coating is made, the cutting process is completed according to the desired length and it is made ready for use.

Conducting Cable Through Spiral Steel Pipe

To pass the cable through the flexible spiral pipe;

Steel spiral cables have guide wires inside. Using these guide wires, the cable can be pulled where it is about to be pulled through the steel spiral hose.
After connecting the guide wire inside the spiral pipes to the electric cable, it is pulled.
Another option is to use susta.
