CharCoat Passive Fire Protection

Cable Coating (Hydrocarbon Rated)

Cable Coating (Hydrocarbon Rated)

CharCoat CC Cable Coating is now the most sought after Cable Fire Protection coating in the market today. Our CharCoat Cable Coating is “built for purpose” in Fire Rating electrical cables and cable systems in Hydrocarbon and non-hydrocarbon environments (currently up to 90 minutes).

For over 20 years CharCoat has been supplying the most up to date solutions to stop electrical cable fires. CharCoat CC, our highly approved Intumescent Latex Cable Coating stops fire from spreading on the cable surface at the source and simultaneously increases the fire resistance of the Electrical Power, Control or Communication Cables. (single, grouped or in tray) for:

      • 90 minutes under IEC 60331-11/21 (1100°C)
      • 90 minutes under IEC 60331-11/21 (750°C)

Indisputably, some of the most dangerous and highly flammable materials in a workplace are Electrical Cables (sheaths). Whether on HV, MV or LV Electrical Cables, fire will spread along the surface of the cable to other areas of the facility; not only spreading fire and causing destruction, but also releasing lethal toxic gases such as hydrochloric gas produced by the burning PVC cables. Couple this with water and you have Hydrochloric Acid, which will spread through a facility rendering all electronics obsolete.

The original function of cable coatings was to prevent flame propagation (spread of flame) and stop the loss of assets due to cable fires. There is no doubt that spread-of-flame coatings do stop fires. However, the cable is then lost to the fire, necessitating cable replacement with ensuing downtime, which can last for weeks.

Spread of flame coatings are applied to stop flame propagation only (IEC 60332-3), they are not installed to save the cable. CharCoatCC on the other hand stops the flame spread and saves the cable. CharCoat CC is not only tested to IEC 60332-3, but also to IEC60331-11 and IEC60331-21 (750⁰C and 1100⁰C). This is a massive difference in protecting the asset and minimizing downtime and cost.

What Does This Mean?

Cables coated with CharCoat CC have continued integrity for up to 90 minutes in a Hydrocarbon based fire (1100°C). CharCoat CC can be applied in petrochemical facilities, offshore platforms, gas plants and chemical plants where hydrocarbons are present.

How Intumescent Coatings Function?

As an Intumescent CoatingCharCoat CC protects through Insulation. It expands under heat and forms an insulating char (up to 800%) that continues to insulate and protect the cable under fire for a period of time. As CharCoat CC is an Intumescent Latex and 100% UV stable (tested and approved for exterior use), it can be applied to exterior cables (salt water exposure testing and UV stability test completed 2016). It is perfect for full exterior application.

As UV is one of the most damaging rays to electrical cable sheaths, application of CharCoat CC on exterior cables will  extend the lifetime of the coated cables without failure. Lifetime extension of the cable is paramount in facilities where re-cabling costs are sometimes financially crippling, but required. By coating the cables with CharCoat CC, facilities protect the sheath from damaging UV rays and can in most instance extend the lifetime of the cable up to 15 years.
