It is widely adopted for insulating wrapping and protection of various wires and cables to avoid short circuits and electric leakage between conductors.
Motor and Electrical Appliance Insulation
It is suitable for insulating treatment on windings of motors, transformers and other electrical equipment to enhance operational safety and reliability.
High-temperature Equipment Protection
It is used for circuit insulation protection of high-temperature furnaces and heating equipment, keeping intact without deformation or detachment under high temperatures.
New Energy Industry Applications
It is ideal for wiring harness insulating wrapping in new energy vehicles, photovoltaic power generation, energy storage and other fields to meet high-standard application demands.
Production Technology
High-quality Fiber Selection:We select premium alkali-free glass fiber fabric as the substrate with evenly arranged fine fibers to lay a solid foundation for stable product quality.
Precise Impregnation and Coating:Advanced impregnation techniques are applied to enable even penetration of insulating coatings into the fiber fabric, ensuring consistent performance of every finished product.
Constant-temperature Curing Process:Strict constant-temperature curing treatment firmly bonds coatings to the substrate to prevent peeling and cracking and guarantee stable overall quality.
Full Roll Inspection before Delivery:All finished products undergo strict appearance and performance tests roll by roll to rule out defects and breakpoints before packaging and shipment.
Usage Instructions
Inspect the insulation tape for damage and dampness before use, and confirm complete and intact coatings prior to wrapping work.
Adopt the half-overlapping wrapping method to achieve full coverage and reliable overall insulating protection.
Apply moderate tension while wrapping to ensure the tape fits closely to conductor surfaces and avoid looseness and detachment.
Thoroughly check all wrapped positions to ensure no exposed conductors are left before connecting the equipment to power circuits.
