Metal hose is used when laying electrical networks to protect the cable from kinks, mechanical damage, exposure to electromagnetic radiation.
Types of metal hoses:
- Galvanized steel: with or without heat-resistant or cotton seal.
- Stainless strip: with or without heat-resistant seal.
The inner diameter of the products ranges from 3.8 millimeters to 100 millimeters, and the outer diameter ranges from 7.6 millimeters to 110 millimeters.
The standard metal hose is made of galvanized steel. Despite the fact that it is made of thin metal, it has a stable breaking strength. The best option to withstand the negative effects of the environment is a stainless steel hose. For security, telephone and other wires, it is recommended to use products characterized by increased strength and a special design of the lock to prevent mechanical damage. A metal hose with a broach protects the cable from various damages, prevents fires in the event of a short circuit, provides a screen from interference in the electromagnetic field, and absorbs all kinds of vibration. It is sealed to prevent dust from getting inside.
When choosing a product, you should calculate the length for each installation case. If you use a hose that is too short or too long, it will damage the termination area. The total length should include neutral sections that will be located near the reinforcement, they are not subject to bending during operation.
