This armored heating wire features a coaxial structure consisting of a “heating conductor—mineral insulation—metal sheath.” It uses a single or multiple alloy heating wires as the heat source, is internally filled with high-purity electrically fused crystalline magnesium oxide as a heat-conducting insulating material, and is externally covered with a seamless stainless steel or copper sheath, all formed as a single unit through processes such as tube shrinking and drawing.Its dense structure provides insulation, thermal conductivity, and external mechanical protection, offering excellent mechanical strength and corrosion resistance; in corrosive environments, a PE or low-smoke, halogen-free outer sheath can be added as needed.The product can be bent into coil or spiral configurations to fit installation spaces, making it suitable for embedded heating in chambers or heating plates, as well as for pipe and tank trace heating, freeze protection, and thermal insulation. It can be equipped with end seals and temperature control/limit protection, facilitating on-site integration and maintenance.

• Industrial Electric Trace Heating and Thermal Insulation: Thermal insulation, anti-condensation, and process temperature maintenance for pipelines, valves, instrument sampling lines, storage tanks, etc.
• Process Industry Heating: Heating of process pipelines, insulation of equipment, and localized supplementary heating in sectors such as chemicals, energy, and metallurgy
• Equipment and Component Heating: Heating modules, heating coils, and heating assemblies (customized by structure for use inside equipment)
• Special Operating Conditions: Heating applications requiring high mechanical strength, vibration resistance, and environmental durability
• Precision Machinery and Medical Instruments: Hot runner systems for injection molding machines, heating of 3D printing nozzles, and internal precision temperature control for medical analytical instruments and chromatographs.
• Semiconductor and Vacuum Equipment: Embedded heat sources within CVD/ALD aluminum or ceramic heating plates; anti-condensation baking of the outer walls of vacuum chambers and process gas piping

• High Flexibility for Conforming to Complex Structures: Features a slim diameter and excellent ductility, supporting three-dimensional bends with small radii. Can be flexibly embedded in narrow assembly spaces or complex metal grooves to meet the needs of irregularly shaped heating surfaces.
• Robust Construction with High Resistance to Pressure and Vibration: The internal mineral insulation powder is compacted through high-frequency rotary forging, securely fixing the heating element in place. The sturdy metal casing enables it to withstand a certain degree of external impact, compression, and mechanical vibration.
• Rapid Heat Transfer and Uniform Temperature Distribution: The extremely short distance between the heating element and the metal outer tube, combined with magnesium oxide’s excellent thermal conductivity, enables a rapid thermal response. Customizable power density distributions are supported, assisting equipment in achieving more precise thermal field control.
• High Temperature Resistance, Suitable for Harsh Environments: Optional stainless steel or high-temperature alloy sheaths are available, offering a wide operating temperature range. The heating element resists oxidation at high temperatures and can operate stably over the long term in industrial environments and vacuum conditions.
• Highly Customizable One-Piece Construction: Supports seamless internal integration of the cold end and hot end during manufacturing, eliminating the need for external splicing. This effectively reduces the risk of electrical leakage and damage at connection points, making installation simpler and safer.
