About Tri-rated Cable

What is Tri-rated cable?

Tri-rated cable, also known as BS6231 control panel wire, is a flame retardant cable suitable for high working temperatures of up to 105°C. Tri-rated cables are used in electrical cabinets, switch control, relay and instrumentation panels of power switchgear.

All of Clynder’s 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.

We carry out rigorous in-house cable testing and also regularly send samples for testing with the approvals bodies, which ensures continual compliance with all three standards. The product’s three ratings put it in high demand globally as the triple certification enables their use both throughout Europe as well as North America.

Some suppliers market Tri-rated cables incorrectly as H05V2-K and H07V2-K, under the European harmonisation (HAR) designation code; however this is not the same product as the standards do not overlap on the smallest three sizes.

Why Clynder Tri-rated?

Clynder Cables offer one of the widest ranges of colours and sizes in the UK, with cable available off the shelf when you need it. The Clynder Cables brand has wide market recognition and the company is an approved supplier to some of the most prestigious names in the UK Electrical Wholesale and Distribution industries.

Many of the leading control panel builders both in the UK and internationally specify our BSI, CSA and UL-approved Tri-rated cable.

As a British cable supplier, we are unique in that we manufacture all of our Tri-rated cables on site in the UK.  We do not dual source, unlike some of the importing UK distributors, which means that our cable never varies in colour or quality.

Customers also recognise Clynder Cables’ Tri-rated for its flexibility, which is due to the special bespoke grade of our PVC compound. Because of this flexibility, the cable does not retain its shape on the reel (the so-called spring coil effect), meaning that the customer can use 100% of the cable.

The colour consistency of our product is unrivalled because we use distinct RAL colour coded compounds from one sole masterbatch supplier. Our extrusion machines are also carefully calibrated so that the cable colour never varies from one batch to the next.

What are Bi-rated cables?

Bi-rated cables are another name for Tri-rated cables above 120mm². They are called Bi-rated as the CSA standard no longer applies to cables of this size. We stock these cables as part of our Superflex range.

What is the Low Smoke alternative to Tri-rated?

For applications requiring a panel wire with a Low Smoke Zero Halogen (LSZH) insulation, Trirated cable is not suitable and therefore we would recommend an alternative cable in our range – 2491B / 6701B.

These panel wires are suitable for equipment in sensitive public areas such as schools and hospitals. They help reduce the overall smoke and toxic fumes in a fire situation, where there could be a threat to life or possible damage to equipment.

Construction

Tri-rated cables have a plain annealed Class 5 single core copper conductor with a high grade heat resistant PVC insulation.
