Usage
Mineral Insulated (MI) Cupro-Nickel heating
cable is suitable for operations with a
maximums sheath temperature of 400⁰C.
MI Cupro-Nickel cables are widely used
within a range of industrial applications,
from oil and gas, chemicals and petrochemical, power generation, gas storage and
many other industrial applications. The Cupro-Nickel copper conductor range (HDC)
has been developed to struggle against severe on-site corrosive environments. This
range has low electrical resistance values required for long pipeline applications.
MI cable features
Corrosion resistance
High performance output
High resistance to mechanical abuse
Safety and fire resistance

Step 1: By design, identify cable reference to be used and calculate Watts/meter
rating of cable/element e.g. HDF1M250, 60Watt/m.
Step 2: Refer to rating factor table and multiply Watts/meter rating of cable/element
by rating factor to obtain adjusted Watts/meter value.( 60W/m x 0.756 = 43.36 W/m)
Step 3: Using adjusted value, enter graph on Watts/meter axis and obtain cable
sheath temperature for application maintain temperature. Cable sheath temperature
= 290⁰C for 100⁰C maintain- see graph.
