CABLE ENTRY

Cable entries for industrial applications

Cable entries They are used to insert cables and wires into devices and enclosures. Depending on the design of the specific solution, they may also be responsible for sealing the cable entry point, securing it, and maintaining the required enclosure properties.

Elektrometal's offering includes cable glands for various industrial applications, including solutions used as components of Elektrometal equipment and certified cable glands for installation in potentially explosive atmospheres. The scope of application of a specific cable gland depends on its design, intended use, and technical documentation.

What is the function of a cable entry?

The cable entry point into the device requires a solution that suits both the housing design and the cable used. Therefore, the cable entry is not merely a means of passing the cable through.

For example cable entry WP 17-23 A is intended for inserting cables and wires into devices manufactured by Elektrometal SA and is certified together with these devices. In turn, in the construction WKE 17-23 inlet a sealing ring and fasteners are used to protect the cable against pulling out and twisting.

This shows that the method of making an inlet should be considered together with its purpose, the diameter of the pipe and the requirements of the device in which it is to be installed.

Cable entries for potentially explosive atmospheres

A separate part of the offer are cable glands intended for use in explosive atmospheres Elektrometal offers, among others, HAWKE solutions suitable for installation in zones 1/21 and 2/22.

An example is HAWKE 501/421 – a single-seal gland designed for specific types of unarmored cables. Also available HAWKE 501/423 with double seal and HAWKE ICG/653/UNIV , the design of which is intended, among others, for specific cables with elastomeric and plastic insulation.

Individual Ex inlets should not be considered interchangeable solutions solely because they are explosion-proof certified. They differ in design, sealing method, cable type, temperature range, and degree of protection; therefore, their use should be determined by the specific product documentation.

Cable entry as part of a device or housing

Cable entries work with other installation elements. For example, in Ex E junction boxes M1 PL They are mounted in enclosure openings and serve to guide wires and cables into the enclosure. This makes it easier to consider the cable entry not as a standalone product, but as part of a specific technical solution.

More devices designed for explosion-proof applications can be found in the category Ex equipment , while the entire group of cable entries is part of a wider offer equipment for industry .

In solutions intended for potentially explosive atmospheres, the material is also helpful How to select devices for the Ex zone , which explains the meaning of markings and conditions of permissible use of devices.
