The Importance of Metal Braid for Electric Heating Cables

The metal braid layer conducts and dissipates heat, enhancing the overall tensile strength of the heating cable. It also serves as a safety grounding wire, which must be grounded to prevent electrical hazards to personnel and equipment from posing a risk of electrical damage to the metal casing of electrical equipment, distribution equipment structures, and line towers. It is suitable for dry, corrosion-free environments and hazardous areas where grounding is required to prevent static induction or sparking.

The outer shielding layer is made of aluminum-magnesium alloy wire or tinned copper wire, requiring a coverage density of 80%. It is often used in explosion-proof areas. It is categorized by layout, typically as an inner shielding layer or an outer shielding layer, distinguished by whether the outer shielding layer has an insulating outer sheath.

Metal shielding mesh with a coverage density exceeding 80% is commonly used in explosion-proof areas. It effectively prevents static electricity and allows for excellent ground contact to prevent sparks, making it particularly suitable for flammable and explosive environments. The metal shielding is a grid-like structure that provides high electrical resistance and enhances the overall tensile strength of the heating cable.

The electric heating cable utilizes a fully enclosed insulating protective layer structure and a temperature-controlled thermoswitch to ensure stable operation within the set temperature range, resulting in ideal operational safety and reliability. Furthermore, the metal shielding mesh within the cable's inner sheath not only enhances mechanical performance but also provides a grounding method for ungrounded pipes, such as plastic pipes. Specifically designed and manufactured for these challenging heating environments, we offer explosion-proof, corrosion-resistant, and self-regulating temperature heating cables.
