RTD Mineral Insulated Cable
Product Description
1. Introduction
- MI RTD cable is used for RTD assembly.
- RTD mi cable , RTD MIC, has a stainless steel or Inconel outer metal sheath with copper or Nickel signal wire conductors.
- The conductor lead wires are insulated from each other and the outer sheath by compacted magnesium oxide MgO.
- Metric and standard US inch diameters are manufactured in a range of OD sizes with 2 ,3 , 4 or 6 wire internal conductors.
- The 4 wire design is produced in wide or standard pattern layout in various diameters.
- Coil lengths of 50 to 1000 ft are typical.
2. Parameters
- Conductor material: NiCr-NiSi, NiCrSi-NiSi, NiCr-Konstantan, Fe-Konstantan, Cu-Konstantan
- Core number: 2, 4 or 6 cores
- Sheath material: SS321(SS304), SS316, SS310, INCL600
- Insulator: 99.6% high purity MgO
- Dia(mm): from 0.5mm to 12.7mm
- RTD MI Cable can be supplied in cut to length MIC wire sections for OEM sensor and probe builders.
- Short straight lengths of MIC RTD MI cable from 4.25 inch to 28 inch can be cut to length CTL.
- Each end of the cut to length MIC can be prepared straight cut or with stripped lead lengths to match your RTD sensor probe assembly requirements.

5. Advantages
Mechanical Strong: The metal sheath and solid filling of MI cable makes it mechanically robust and resistant to impact, can work in hazardous environment.
Waterproof: Copper sheathing is waterproof and resistant to ultraviolet light and many corrosive elements. MI cable is approved by electrical codes for use in areas with hazardous concentrations of flammable gas in air.
Fireproof: MI cable can withstand very high temperatures (higher than 1000°C), since all its components are inorganic. It can go on working during a fire, maintaining power to all emergency services, allowing all safety and protection measures within the building to be activated.
