Series Constant Watt Heating Cable

MIQ high performance mineral insulated heating cables are used extensively for high temperature maintenance, high temperature exposure and/or high watt density applications which exceed the limitations of thermoplastic insulated cables. The resistance configurations available can provide tracing for pipes up to 1.6 km (1 mile) long from a single power supply point. Thermon’s MIQ mineral insulated cables are manufactured using Alloy 825, a high nickel/chromium alloy ideally suited for high temperature service that offers exceptional resistance to stress corrosion in chloride, acid, salt and alkaline environments. APPLICATION MIQ high performance mineral insulated heating cables are used extensively for high temperature maintenance, high temperature exposure and/or high watt density applications which exceed the limitations of thermoplastic insulated cables. The resistance configurations available can provide tracing for pipes up to 1 mile (1.6 km) long from a single power supply point. Thermon’s MIQ mineral insulated cables are manufactured using Alloy 825, a high nickel/chromium alloy ideally suited for high temperature service that offers exceptional resistance to stress corrosion in chloride, acid, salt and alkaline environments. MIQ cables are approved for use in ordinary (nonclassified) areas and hazardous (classified) areas.

Notes 1. Definition as stated in IEEE Standard 515. Specific voltage depends on circuit length and design conditions. 2. Watt density limitations are correlated to maintain temperatures. 3. Contact Thermon for gland size information. 4. If the field is blank, then the heating cable set is intended for ordinary (nonclassified) locations or Division 2 locations, or for use with AEx de, or Ex e enclosures. If the value in the field is “1”, then the heating cable set is intended for Division 1 locations, or for use with AEx d, or Ex d enclosures. CONSTRUCTION 1 Solid alloy or copper conductor(s) 2 Compacted magnesium oxide insulation 3 Seamless alloy 825 sheath MIQ HEATER SETS Thermon MIQ cable sets are available in four factory fabricated configurations: Type A, B, D or E. The standard assemblies consist of a predetermined length of heating cable joined to a standard 4’ (1.2 m) or 7’ (2.1 m) nonheating cold lead with 12” (305 mm) long thermoplastic insulated pigtails. The nonheating section of the unit is sealed and fitted with a high pressure, liquid-tight 1/2” or 3/4” NPT stainless steel gland 3 for connection into the supply junction box. CIRCUIT BREAKER SIZING 2 Maximum circuit lengths for various circuit breaker amperages are shown. Breaker sizing should be based on the National Electrical Code, Canadian Electrical Code or any other applicable code. The National Electrical Code and Canadian Electrical Code require ground-fault protection of equipment for each branch circuit supplying electric heating equipment. Che
