About Tri-rated Cable

Tri-rated cable (BS6231 control panel wire) is a flame retardant cable that can be used in high working temperatures up to 105°C. Tri-rated cables are used in switch control in relay and instrumentation panels of power switchgear and in electrical cabinets.

All of our Tri-rated cables carry the three approval ratings – UL (Underwriters Laboratories), CSA (Canadian Standards Association) and BSI (British Standards Institution), hence the name Tri-rated. Cable is tested in-house and samples are sent regularly to the approvals bodies to ensure continual compliance with all three standards.

The product’s three ratings put it in high demand globally as the triple certification enable their use throughout Europe as well as North America.

Tri-rated cables are sometimes sold incorrectly as H05V2-K and H07V2-K, under the European harmonisation (HAR) designation code; however this is a different cable type – 2491X HR, which we also supply.

Tri-rated cable and H05V2-K / H07V2-K are not the same, as the standards do not overlap on the smallest three sizes.

Clynder Cables is a leading tri-rated cable supplier offering one of the widest ranges of colours and sizes in the UK. Our BS, CSA and UL-approved tri-rated cable is widely used by leading control panel builders nationally and internationally, The Clynder Cables brand is a widely-recognised name and an approved supplier to some of the most prestigious names in the UK Electrical Wholesale and Distribution industries.

As a British cable supplier, we are unique in that all of our Tri-rated cable is manufactured on site in the UK, with rigorous in-house testing in our laboratory to ensure the quality of your products and installations. Also, unlike some UK distributors, we do not dual source, so our cable never varies in colour or quality from one batch to the next, and with the flexibility of our compound, the cable does not retain its shape on the reel (the so-called spring coil effect), meaning that 100% of the cable on the reel can be used.

Cables above 120mm² in size are known as Bi-Rated as the CSA standard no longer applies. We stock these cables as part of our Superflex range.

For applications requiring Low Smoke Zero Halogen (LSZH) insulation, Trirated cable is not suitable and alternative panel wire must be used. These include 2491B / 6701B (H05Z-K / H07Z-K). These panel wires are often used for equipment in sensitive public areas such as schools and hospitals to prevent the smoke and toxic fumes in a fire situation, where there could be a threat to life or possible damage to equipment.

Construction

Tri-rated cable is constructed with a plain annealed Class 5 single core copper conductor and a single layer high grade heat resistant PVC insulation. Clynder Cables is renowned for the flexibility of our Tri-rated cable due to the bespoke grade of the PVC compound we use, and also for the colour consistency of our product, which never varies from one batch to the next.
