When wiring electronic appliances and low-voltage equipment, choosing insulation tubing can often be a headache: cable jams, poor environmental resistance, and high costs... Traditional tubing, due to its negative tolerance design, can easily get stuck during wiring, and it easily hydrolyzes and deforms in humid environments. It also struggles to balance flexibility and flame retardancy.

 
As a fiberglass sleeving manufacturer with 20 years of production experience, Volsun innovative "medium-alkali glass fiber woven tubing + PVC resin coating" structure perfectly addresses these pain points. It not only offers positive tolerance adaptability, VW-1 flame retardancy, and stability in humid environments, but also provides a flexible, reliable, and cost-effective solution for medium- and low-voltage insulation applications ranging from 1.5kV to 4.0kV.
 
Let's take a closer look at its advantages.
 
First, the PVC fiberglass sleeving features a fully positive tolerance design, with an inner diameter range of Ø0.8mm to 35.0mm, ensuring smooth, no-stuck wiring. It's particularly suitable for multi-strand or connectorized wire installations, significantly improving assembly efficiency.
 
Second, its environmental resistance is exceptional: with a heat resistance of 105°C ± 2°C and an operating temperature range of -10°C to 100°C, it easily handles environments with large temperature and humidity fluctuations. Furthermore, it holds a UL94 VW-1 flame retardancy rating and self-extinguishes when exposed to open flames, effectively reducing the risk of fire.
 
Furthermore, the combination of PVC coating and fiberglass sleeving provides a product with both flexibility and resilience. It passed the IEC60684 cold bend test without cracking, perfectly conforming to curved wiring within devices and is suitable for densely packed wiring environments such as routers and power adapters, without creases or coating peeling.
 
Finally, the PVC fiberglass sleeving exhibits excellent hydrolytic stability, resisting stickiness, deformation, and softening, making it particularly suitable for protecting cables in humid environments such as washing machines and range hoods. VW-1 flame retardancy meets the fire safety standards of various electronic appliances, with a volume resistivity of 10¹¹Ω·cm. Its stable insulation performance effectively prevents the risk of electrical leakage.
 
This PVC fiberglass sleeving has a wide range of applications, from headphone cables and charger internal leads in consumer electronics to main wiring in washing machines and range hoods in household appliances, sensors and low-voltage relay wiring in industrial control systems, and even branch cables in low-voltage distribution boxes. PVC fiberglass sleeving offers precisely matched specifications and voltage support, achieving "one line, one tube, peace of mind."
 
Volsun PVC fiberglass sleeving is available in a full range of sizes, with inner diameters ranging from Ø0.8 to 35.0 mm and voltages covering 1.5 kV to 4.0 kV. Wall thicknesses are precisely matched to specifications. Choosing Volsun PVC fiberglass sleeving makes medium and low voltage insulation simpler, more reliable, and more economical.
