nVent RAYCHEM XMI-A (Alloy, 825) electric heat trace cable is a metal sheathed, mineral insulated (MI) cable designed to provide heat tracing solutions for a variety of industrial applications. MI heat trace cable is often used where high power output, high exposure temperatures, or extreme resistance to environmental corrosives is needed. Typical applications include: Pipe Freeze Protection, Process Temperature Maintenance, Longline Heating. RAYCHEM XMI-A MI electric heat trace cables can provide up to 61 watts per foot (200 watts per meter) of power output with area classification and design approvals. The maximum maintain temperature for MI heat trace cable is 1022°F (550°C) and the maximum exposure temperature for the heating cable is 1200°F (650°C).

Additional Product Information:

  1. Higher temperature capabilities are available (please contact your nVent sales representative for additional information)
  2. Approved for use in nonhazardous and hazardous locations for most applications

Technical Specifications

  1. The XMI-A heating cables are constructed using an Alloy 825 sheath consisting of either single or dual heating conductors covered with a magnesium oxide insulation. They are ideally suited for heating applications where high power output, high exposure temperatures, or extreme resistance to environmental corrosives is needed.
  2. The heating cable shall have a maximum maintain temperature of 1022°F (550°C) and a maximum continuous exposure temperature of 1200°F (650°C). Higher temperature/power capabilities may also be available depending on the application; contact nVent Industrial Heat Tracing Solutions for additional information.
  3. The heating cable shall be available as 300 V and 600 V rated heating cables that are approved for applications up to 61 watts per foot (200 watts per meter) of power output, and can be used for pipe and vessel tracing in both hazardous and nonhazardous area applications.
  4. The Temperature ID Number (T-Rating) shall be established by calculating the maximum sheath temperature; contact nVent Thermal Management Building Solutions for assistance.
  5. Depending on the specific application, the XMI-A heating cables are designed as engineered heating units which consist of a length of heating cable (Heated length) joined to a length of non-heating cold lead (Cold lead length).
  6. The cold lead is selected based on the voltage and current requirements of the XMI-A engineered heating unit. These cold leads shall be supplied from the factory with a standard stainless steel National Pipe Thread (NPT) gland connector ready for assembly into the junction box or panel using the flexible wire tails extending from the MI cold lead.
