Utilization	Machine installation conduit MI 30

The SKMIR 30 protective ring from Niedax is a component specifically developed for cable protection conduit systems, designed as a protective cap for machine installation conduits MI 30. It serves to secure cables and wiring at locations where personal hazard due to mechanical impact or contact exists. The protective cap is made of polyethylene (PE), a robust plastic known for its chemical resistance and mechanical strength. The protective ring is yellow in colour, making it visually identifiable and contributing to the marking of protective measures. The length is approximately 32 mm, providing sufficient coverage for the conduit opening.

Applications

The SKMIR 30 protective ring is primarily intended for use in machine installation conduit systems, particularly for the MI 30 conduit. It is mounted in areas where personnel could be endangered by exposed cable ends or conduit openings, for example, on machines, plants, or in production environments. Installation follows occupational safety guidelines to prevent mechanical injuries from contact or pinching. Its use is particularly relevant in industrial plants and during the installation of control and power wiring.

Functions and Equipment in Detail

The protective cap acts as a mechanical closure for the cable protection conduit, preventing cable ends or conduit openings from becoming hazard sources. It is halogen-free, meaning that in the event of heating or combustion, no toxic halogen compounds are released. This is especially important in enclosed spaces or when used in electrical installations. The polyethylene (PE) material offers good resistance to moisture, chemical influences, and mechanical stress, increasing the longevity of the protective ring.

Technology Explained Simply

The protective ring is slipped over the end of the MI 30 machine installation conduit and serves as a fixed cover. The yellow colour acts as a visual identifier and supports recognisability during operation. The length of approximately 32 mm ensures that the ring extends sufficiently beyond the conduit to allow for safe coverage. The PE material is a thermoplastic polymer that is hard and impact-resistant at room temperature, yet becomes malleable when heated – a property that can be helpful during installation. The halogen-free composition reduces fire hazard and the formation of toxic gases in the event of a fire.

Compatibility and Accessories

The SKMIR 30 protective ring is specifically designed for the MI 30 machine installation conduit. It is therefore directly compatible with this conduit size and is used in combination with the conduit to ensure safety at the ends of the wiring.

Installation and Mounting

Installation is carried out by simply sliding the protective ring over the open end of the MI 30 machine installation conduit. No additional fastening or tools are required. Installation takes place at locations where personal hazard exists, in accordance with occupational safety regulations. The protective cap must fit securely to prevent mechanical stress or contact.

Operational Advantages

The SKMIR 30 protective ring offers a simple and effective solution for securing cable protection conduits. The halogen-free composition increases safety in the event of fire, while the robust PE construction ensures long service life and resistance to environmental influences. The yellow colour supports visual recognisability, facilitating maintenance and inspection. The tool-free installation reduces installation effort and the risk of errors.
