Maximum bending radius: 6 times the cable diameter
The V2L cable is a cable in which the power supplied does not vary as the temperature varies. The cable must be powered at both ends and the power supplied is determined by the well-known Joule formula: W= V2/ρ x L.
ere:
– W is the power supplied by the entire heating circuit
– ρ is the resistivity in ohm/m of the heating cable used
– L is the length of the heating circuit in m
The mineral insulated cable is constructed from a resistive nickel-chrome conductor insulated with magnesium oxide and an outer metal ALLOY600 sheath.
These cables cannot be cut and spliced to vary the length of the circuit from that determined at the time of sizing. Varying the length of the heating circuit results in a variation of the power supplied with the danger of subjecting the cable to excessive temperatures with consequent damage or having less power available than required. These cables always require a control thermostat to prevent over-temperatures which would cause damage
For installations in an ATEX zone, the temperature control must be carried out in accordance with the regulations in force.
Maximum sheath temperature based on model:
Example: 0.63V2L-45 with power 228.4 W/m in environment at 200°C; equivalent power 228.4 x 0.769 = 175.6 W/m approx.
