Washer for cable clamp BS 30-40 GW-40

Cable Diameter Protection and Adaptation

When electrical installations contain cable bundles with diameters close to the lower limit of the clamp's range, standard mounting may not guarantee full stability. In such cases, using an additional filler element between the cable and the clamp becomes crucial. The GW-40 washer is precisely such a solution – a component made of polypropylene (PP) that enables effective securing of cables with diameters from 30 to 40 mm in BS-type clamps. This eliminates the need to use smaller clamps or risk the cable "slipping" inside the mounting during operation or under vibration.

The material used for this accessory is polypropylene – a plastic known for its resistance to mechanical damage and dimensional stability. It is therefore not a cheap substitute, but a component with technical properties adapted to conditions found in switchgear or control cabinets. The washer acts as an adapter: it fills the gap, allowing the BS 30-40 clamp to securely grip even thinner cables while maintaining its protective and organizational function.

Practical Application and Installation

Installing this component is simple and requires no specialized tools. The washer is designed to be used in conjunction with BS series clamps with a range of 30–40 mm. Simply place it inside the clamp before inserting the cable or cable bundle. This ensures:

• Increased contact surface between the clamp and the cable, improving grip;
• Elimination of gaps that could lead to insulation abrasion under prolonged external forces;
• Simplified installation organization, allowing the use of a single clamp type for various cable diameters (within the specified range).

It is worth noting that this washer is supplied in bulk packages containing 10 pieces. This solution is convenient for installers working on larger projects where multiple mounting points may need adjustment simultaneously. There is no need to purchase individual components – the ready-made set allows quick replenishment of missing links in the cable management system without interrupting work to order additional batches.

Compliance with Technical Requirements

This product meets the basic requirements for mounting accessories in the electrical industry. Its polypropylene-based construction provides adequate chemical and thermal resistance for most standard operating environments. There are no metal components here that could corrode or cause additional mechanical stress – the plastic is lightweight and resistant to moisture and many chemicals found in technical rooms.

For professionals, this means confidence that once the washer is installed, the mounting system will perform according to design specifications throughout the installation's service life. For the end user, it simply means a neatly arranged and safe installation where cables are held exactly where they should be – without gaps or risk of insulation damage.
