Insulating tape material hrang hrangte hian physical leh chemical property danglam tak an nei a, application scenario bik atanga tehin match bik an mamawh a ni.
Polyvinyl chloride (PVC) tape is currently the most widely used insulating material. Its advantages lie in its excellent electrical insulation performance (breakdown voltage exceeding 6000V), good weather resistance, and flexibility. PVC tape, whose hardness is adjusted by adding plasticizers, is suitable for insulating conventional low-voltage lines. However, it is susceptible to softening and deformation in long-term high-temperature environments (>80℃a ni ).
