RAYCHEM LSZH jacketed copper-sheathed mineral insulated (MI) series resistance trace heating cables are specifically designed for various low-temperature maintenance applications. These applications include embedded heating in concrete or asphalt, roof de-icing, frost heave protection, exposed snow melting, and interior pipe tracing. MI Jacketed Copper Industrial Heating Cables are capable of withstanding continuous exposure temperatures up to 194 °F/90 °C and delivering typical power outputs reaching 35 W/ft (115 W/m depending on application.) Notably, these cables are approved for embedded and roof de-icing applications within hazardous areas.
In scenarios where corrosion or embedding is a concern, such as concrete or asphalt snow melting, the cable is equipped with a Low-Smoke Zero-Halogen (LSZH) jacket. The red LSZH jacket, particularly for embedded applications, enhances cable visibility during concrete or asphalt placement, ensuring ease of installation and monitoring. The copper sheath not only serves as an ideal ground path but also contributes to a robust yet flexible heating cable that is simple to install. Each heating cable comprises a heated section connected to a preterminated non-heating cold lead, ready for connection into a junction box.
