Galvanized steel flexible hose (PESZEL) WSO DN20 (17mm/20.5mm), coil 30m S1005

Robust cable protection in harsh conditions

This galvanized steel hose, commonly known as PESZEL WSO, is a reliable solution for securing electrical cables in areas exposed to intense mechanical damage. Its durable construction makes it ideal for industrial applications, machine and equipment connections, and anywhere high resistance to external factors is required. Thanks to the hose's flexibility, it can be routed freely even with moving machine parts.

Construction and properties

The WSO hose is made of profiled galvanized steel strip, which provides high corrosion resistance and long-term operation. This material is also characterized by a wide operating temperature range – from -45°C to +150°C – allowing it to be used in various environments. The hose is non-flammable and exhibits high resistance to compression (1250N) and impact (2.0 kg/300mm), guaranteeing effective cable protection against damage. The flexible construction facilitates installation and adaptation to specific installation conditions.

Applications and compliance with standards

The steel WSO hose is widely used in industrial installations, public buildings, and anywhere high protection of electrical cables is required. It can be used in internal wall installations (not exposed to direct sunlight), as well as in gypsum walls and on flammable surfaces. The product meets the requirements of Directive 2014/35/EU (LVD), confirming its safety of use. Available in a nominal diameter of DN20 (17mm/20.5mm), supplied in a practical coil with a length of 30 meters.
