Constant Wattage Heating Cables are ideally suited for applications where watt density is required at all times. The heater element consists of a nichrome wire wrapped around, parallel insulated buss wires. At specific intervals, a short section of insulation is removed from alternating buss wires to create connection nodes for the nichrome wire. The nichrome wire is soldered to the buss conductors, creating a network of parallel resistors along the entire length of constant wattage cable. They can be designed to operate at specified voltages between 120- 800 Volts AC/DC. Constant watt cables are an ideal choice for higher temperature applications where high watt densities are required. The PFA jacket and Nickel plated
Copper braid provides additional protection for use in corrosive and hazardous areas.
Constant watt cables maintain their integrity in temperatures up to 482°F (250°C), and can be exposed to intermittent temperatures of 500°F (260°C) maximum. The heating zones of constant watt cables create an extremely rugged heat source that can withstand thermal shock and movement.
