Why Wrexham Mineral Cable

 

Wrexham Mineral Insulated Cable is totally Inorganic and Silicone free in construction. The main construction consists of solid copper conductors (cores), highly compressed powdered magnesium oxide insulation (MgO) and a solid copper sheath. This unique construction gives melting points of 1083°C and 2800°C for the copper and insulation respectively. This provides fire survival whilst continuing to safely carry a load in temperatures in excess of 1000°C

Uses:

Mineral Insulated Cables are used to provide circuit integrity for power and control circuits of critical equipment such as:

  • Nuclear reactors
  • Air pressurisation system for stairwells
  • Hospital operating rooms
  • Fire alarm systems
  • Emergency power systems
  • Emergency lighting systems
  • Sprinkler systems
  • Temperature measurement devices; RTD's, thermocouples
  • Critical process valves - petrochemical industry
  • Public buildings e.g. theatres, cinemas, hotels, schools
  • Transport hubs - railway stations, airports etc
  • Tunnels and mines
  • Hazardous areas where flammable gases may be present
  • Building plant rooms
  • Power stations, foundries
  • Close to or inside industrial foundries, kilns and ovens

Features & Benefits:

Fire Resustant

Fire Resistant

Will neither burn nor support combustion.

High Mechanical Strength

High Mechanical Strength

Withstands considerable stresses such as bending, twisting and flattening, even in a fire situation.

High Operational Temperatures

High Operational Temperatures

Continuous operating temperature up to 250°C and for shorter periods up to 1083°C, the melting point of copper.

Earth Continuity

Earth Continuity

Our cables do not require a separate earth continuity conductor as the outer copper sheath serves this purpose providing excellent low resistance earth continuity.

Inherent Flameproof Barrier

Inherent Flameproof Barrier

With a non-flammable copper sheath the highly compacted insulation will resist the transmission of vapours, gases and flames between items of equipment connected by the cable.

Pliable

Pliable

Mineral insulated cable is fully annealed and consequently extremely ductile and easily manipulated to follow existing wiring routes and irregular shapes.

Non-Ageing

Non-Ageing

Mineral insulated cable is permanent and does not weaken or degrade with age offering longer and safer life spans.

Small Overall Diameter

Small Overall Diameter

Our cables have a smaller diameter than soft skinned fire resistant cables of equivalent ratings.

Air tight

Air tight

Impervious to water, oil and gas.
