Why Wrexham Mineral Cables?

Wrexham Mineral Insulated Cables are totally Inorganic and Silicone free in construction.

The main construction consists of copper conductors (cores), highly compressed magnesium oxide (insulation) & a Copper Sheath with an optional Low – Smoke outer serving.

This unique construction gives melting points of 1083ºc & 2800ºc for the copper and Insulation respectively. This provides fire survival whilst maintaining circuit integrity in temperatures in excess of 1000ºc

The construction of Wrexham Mineral cable gives mechanical strength whilst remaining pliable.

Mineral cable is a non ageing cable with a high corrosion resistance, completely waterproof which gives a high degree of electrical screening

All manufactured Wrexham Mineral cable has passed European and world wide standards Including:

  • BS EN 50200 Class PH120
  • BS EN 50267
  • BS EN 5839-1 Enhanced standard
  • BS EN 60702-1
  • BS 6387
  • BS 8434
  • IEC 60331

Mineral Insulated cables are used to provide circuit integrity for power and control circuits of critical equipment, such as the following examples:

  • Nuclear reactors
  • Air pressurisation systems for stairwells to enable building egress during a fire
  • Hospital operating rooms
  • fire alarm systems
  • Emergency power systems
  • Emergency lighting systems
  • Sprinkler systems
  • Temperature measurement devices; RTD's and Thermocouples.
  • Critical process valves in the petrochemical industry
  • Public buildings e.g. theatres, cinemas, hotels, schools
  • Transport hubs (railway stations, airports etc)
  • Tunnels and mines
  • Areas where flammable gases may be present e.g. oil refineries, petrol stations
  • Areas where corrosive chemicals may be present e.g. factories
  • Building plant rooms
  • Hot areas e.g. power stations, foundries, and close to or even inside industrial furnaces, kilns and ovens.
