1.5KV Black Glass Fiber Sleeve is a cost-effective insulating protective sleeve suitable for concealed wiring of low-voltage electrical equipment. This 1.5KV Black Fiberglass Sleeve is precision-woven from high-purity alkali-free glass fiber, with the outer layer coated with a special black insulating and flame-retardant coating and formed by high-temperature setting. It can stably withstand a 1.5KV high-voltage breakdown voltage, building a reliable insulation protection barrier for low-voltage electrical circuits. The black appearance is more suitable for the concealed wiring needs inside equipment, combining practicality and aesthetics. The Black 1.5KV Glass Fiber Sleeve has excellent electrical insulation performance, which can effectively isolate current leakage, avoid potential safety hazards such as short circuits and electric leakage in the wiring of small home appliances, low-voltage control cabinets, automation equipment, etc., and is the preferred material for concealed insulation protection under low-voltage working conditions.
