Duratherm has developed a series of standard cable heater configurations featuring a rugged, high performance, swaged-on transitions. This transition design features compacted internal ceramic insulation combined with a swaged in silicone seal plug which provides moisture and contamination resistance. High temperature ceramic insulation fully encapsulates the critical cable and lead connection area. The machined and swaged-on transition configuration provides a rugged, abuse resistant transition ideal for cable heaters supplied in straight lengths for customer forming. This transition is also available as an option for preformed or coiled cable heater configurations. This transition construction provide the highest level of mechanical protection and dramatically improved moisture resistance. The seal protects the element from contamination during operation and minimizes moisture absorption during storage.
The standard swaged-on transitions with silicone seal and Teflon* PFA leads are rated at 500° F. (260° C.) continuous.
High performance features of the swaged transition include the following:
1. Superior seal – Swage compressed silicone seal in combination with inorganic sealant resin provides excellent resistance to moisture. The inorganic sealant treated seal protects the element from contamination during operation and eliminates moisture absorption during storage.
2. Heat resistant – Swaged-on transitions with silicone seal and Teflon* PFA leads are rated at 500° F. (260° C.) continuous.
3. High strength – Swaged transition construction is extremely resistant to physical damage and breakage, provides high pull strengths and is well suited for all cable heater applications.
4. Higher Current Rating – The swaging process compacts ceramic around the power conductors, increasing the rate of heat transfer and raising the effective current carrying capacity of the transition. Ideal for high wattage cable heater applications.
5. Versatile – Swaged cable heater transitions provide a rugged, high performance lead exit system accommodating fiberglass sleeve, wire braid and armor lead protection. Options include molded in fiberglass sleeve and wire braid protection.
6. Lower cost – Swaged construction eliminates time consuming operations required for potted style transitions.
