Double sheathed round 3 core and 4 core cables are ideally suited for heavy duty application like sewage, slurry and dewatring pumps in which the sheathing must be able to withstand abrasion, preventingress of water along the interstices of the cable, and be resistant to acidic fluids & reactive base chemicals.
Operating temp. : -10 °C to 70 °C
Voltage Grade up to : 1.1 kV
Requirement of oxygen in air to catch fire: more then 29.5%
Temperature required to catch fire (with 21% oxygen): more then 250 °C
Visibility during cable burning: less then 30%
