Harnawa Insulations Private Limited

Fiberglass Braided Cables are engineered for high-performance electrical transmission in environments subjected to extreme heat, abrasion, and mechanical stress. Each cable is constructed with a core of high-conductivity copper or tinned copper, tightly insulated with heat-resistant fiberglass braiding that provides both thermal stability and electrical insulation. These cables are capable of withstanding continuous exposure to elevated temperatures, often up to 450°C, while maintaining integrity against flames, oil, and wear. The braided fiberglass layer not only ensures superior dielectric protection but also enhances mechanical robustness in dynamic or high-vibration environments.

These cables are widely employed in industrial sectors such as metallurgy, power generation, electric furnaces, welding systems, motors, and heavy-duty machinery, where conventional wire insulation fails due to heat or friction. Their excellent flexibility allows for easy routing in confined spaces or applications with repetitive motion, making them a preferred choice for equipment exposed to mechanical flexing. Available in various voltage ratings and color-coded jackets, Fiberglass Braided Cables can be customized for different circuit applications, simplifying installation and maintenance while ensuring long-term reliability under the harshest operational conditions.

DMD / DMDD Cables are high-performance insulation cables constructed using multiple layers of polyester film and non-woven polyester fabric, bonded with high-grade resin to form a composite insulation material. These cables are engineered to provide superior dielectric strength, thermal endurance, and mechanical integrity, making them ideal for low to medium voltage electrical windings. The DMD (Class B - 130°C) and DMDD (Class F - 155°C) insulation systems offer excellent resistance to thermal aging, moisture, and mechanical stress, ensuring reliable operation in motors, transformers, and electrical apparatus even under continuous load conditions.

Manufactured on advanced high-speed production lines at Harnawa and subjected to rigorous quality control—covering incoming materials, in-process monitoring, and 100% high-voltage inspection—these cables are guaranteed to be defect-free throughout their service life. Their consistent quality and reliability make them a trusted choice for use in transformer winding, electric motor insulation, lighting ballasts, and other electromagnetic applications. Widely adopted in the power, automotive, and industrial sectors, DMD/DMDD Cables deliver long-term electrical insulation performance, while supporting energy-efficient and compact winding designs.

Fiberglass Braided Silicone Cables are advanced flexible wiring solutions engineered for environments that demand a combination of heat resistance, mechanical durability, and electrical insulation. These cables feature a silicone rubber core known for its high thermal stability, remaining flexible across a wide temperature range (typically -60°C to +180°C), while the outer braided fiberglass sheath provides additional protection against abrasion, flame, and mechanical stress. This dual-layer insulation system ensures reliable performance in dynamic conditions where conventional cables may crack, melt, or degrade under thermal or physical strain.

Widely utilized in applications such as electric motors, lighting fixtures, power transformers, control panels, and household appliances, these cables deliver dependable electrical performance while offering ease of installation due to their pliability. Their flame-retardant, moisture-resistant, and chemically inert properties make them especially suitable for industrial automation, HVAC systems, and automotive electrical assemblies. Available in various gauges, colors, and configurations, Fiberglass Braided Silicone Cables are a versatile and durable choice for a broad spectrum of electrical and thermal wiring needs in both commercial and industrial settings.

Fiberglass Mica Cables are specialized high-temperature cables engineered to deliver uncompromised performance in fire-prone and high-voltage environments. These cables feature a multi-layered insulation system comprising mica tape—renowned for its exceptional flame resistance and dielectric strength—combined with an outer braided fiberglass layer that enhances mechanical protection and thermal stability. This construction enables the cables to withstand extreme temperatures, often exceeding 750°C, while maintaining insulation integrity under direct flame, arcing, and high-stress electrical conditions. The mica layer acts as a fire barrier, ensuring circuit continuity even during prolonged exposure to intense heat or combustion.

Designed for the most demanding applications, Fiberglass Mica Cables are widely used in power plants, furnaces, refineries, high-voltage switchgear, and critical control systems where fire safety and operational continuity are paramount. Their ability to resist flame propagation, electrical arcing, and thermal breakdown makes them an essential component in emergency systems, fire-rated panels, and mission-critical power infrastructure. Industries such as energy generation, metallurgy, petrochemicals, and infrastructure development depend on these cables to ensure reliable power delivery and fail-safe performance in the harshest environments.
