 MI Cable

MINERAL INSULATED (MI) CABLE - 600V, MO Insulation, Copper Shealth, HDPE Jacket (optional), 550°C

MI Cable is mineral insulated heating cables that are designed for a wide range of applications, including pipe freeze protection, process temperature maintenance, roof and gutter de-icing, snow melting and floor warming. The copper sheath allows for a rugged yet flexible heating cable, which is easy to install, and the low resistance of the copper provides an ideal ground path. For applications that require additional protection, such as concrete or asphalt snow melting, the copper MI heating cable is coated with a high density polyethylene jacket. MI is also used where high power output, high exposure temperatures, or extreme resistance to environmental corrosives are needed.

     CW Cable

    CONSTANT WATTAGE (CW) CABLE - 400V, 480°C

    Constant Wattage Cable consists of two parallel bus wires encased in a jacket with a wire heating element wrapped around the jacket and soldered to alternating bus wires. The wire and jacket are then encased in an insulating jacket.

  • Continuous output along heated length
  • Cut-to-length and field terminate
  • No degradation
  • No inrush current reduces power feed requirements
  • High exposure and maintenance temperatures
  • Hazardous location ratings
  • Maximum continuous conductor temperature: 480°C

     SR Cable

    SELF REGULATING (SR) CABLE - 277 Volts, Jacket And Metallic Overshield, Two Parallel Bus Wires, 250°C

    Since their introduction in 1971, self regulating heating cables (also known as self limiting heating tapes) have become the most common form of electric trace heating cable used in the world today. They can be used for a wide variety of applications including freeze protection of pipework and vessels, process temperature maintenance, heating of roads, ramps, walkways etc, gutter and roof heating, & floor warming. Self regulating (SR) cable is specified for applications requiring heat output to vary with changes in temperature. SR increases heat output as temperature decreases, and conversely, decreases heat output as temperature increases. SR Cables consist of two parallel bus wires encased in a self regulating conductive core with a jacket and metallic overshield.

  • Continuous output along heated length
  • Cut-to-length and field terminate
  • Easily overlapped with no burnout
  • Hazardous location ratings
  • Maximum continuous conductor temperature: 250°C
