Mineral Insulated Cable (MAL)
The MAL range of alloy 825 sheathed Mineral Insulated (MI) heating cable has been developed to meet the specific need for a cable having a high temperature capability and electrical resistance values needed for long circuit lengths. To meet the requirement, Heat Trace has combined an alloy 825 sheath with heating conductors to enable an operating temperature of 800ºC with resistance values from 2.1Ω/km up to 36100Ω/km per conductor. MI cables have excellent mechanical strength and are intrinsically very resistant to corrosion. They are series resistance heaters which must be designed to provide the required heat output.


Example of Applications
- Freeze protection of high exposure pipelines (e.g. steam manifolds)
- Temperature maintenance of pipelines
Benefits
- Circuit lengths up to 5-6km
- Suitable for single or 3 phase applications
- Metal jacket for increased mechanical strength and fire resistance
