Harnawa Insulations Private Limited

Fiberglass Heater and Sensor Cables are precision-engineered to meet the demands of high-temperature applications where reliable thermal performance and accurate signal transmission are critical. Constructed with high-purity metal conductors—such as nickel, copper, or thermocouple alloys—these cables are insulated with tightly braided fiberglass that offers outstanding thermal resistance, flexibility, and dielectric protection. Capable of withstanding continuous operation in environments exceeding 450°C, the fiberglass insulation not only protects against degradation from heat and flame but also shields the conductors from physical wear and chemical exposure.

These cables are widely utilized in temperature sensing, heating elements, and process control systems across industries such as metallurgy, ceramics, power generation, and chemical processing. They are ideal for integration into industrial heaters, ovens, kilns, thermocouples, and laboratory equipment, where consistent signal integrity and thermal stability are vital. Their rugged design ensures long service life even under frequent thermal cycling, vibration, or abrasion, making them a dependable solution for mission-critical temperature monitoring and control in challenging industrial environments.

Equipped with sophisticated and imported high-speed lines, Harnawa produces a wide variety of DMD cables for various applications. Entire production process passes through stringent quality checks at incoming and in process3 stage for quality output. 100% high voltage inspection ensures zero defects throughout the life cycle.
