In high-tech equipment such as new energy vehicles and rail transit, the stability and safety of electrical systems depend on reliable insulation protection. Ordinary tubing is particularly susceptible to aging, cracking, and even failure under complex operating conditions such as high temperature, high humidity, and strong vibration. The Volsun NS-GF200RUB-D silicone rubber fiberglass sleeving, with its "glass fiber braid + silicone rubber coating" composite structure, offers a perfect combination of high-temperature resistance and flexibility, making it an ideal choice for high-temperature insulation applications.

The most notable feature of this fiberglass sleeve is its exceptional stability in extreme temperatures. It maintains performance across a wide temperature range of -40°C to 200°C. Even after being exposed to the harsh cold of northern China for over four hours, it remains flexible and resistant to cracking or coating loss. Furthermore, in sustained high-temperature environments, such as those found in the engine compartments of new energy vehicles, it can withstand temperatures of up to 200°C for extended periods without thermal aging, maintaining stable insulation performance. This resistance to temperature fluctuations and aging significantly extends the cable's service life and reduces equipment maintenance frequency.

In addition to its excellent temperature resistance, the NS-GF200RUB-D fiberglass sleeve also boasts exceptional mechanical strength. Its tear strength exceeds 50N/mm, significantly exceeding that of ordinary sheathing materials. It resists mechanical stresses such as wiring installation and equipment vibration, making it less susceptible to breakage. Furthermore, its smooth, abrasion-resistant surface effectively protects the cable from scratches and tugs during daily maintenance. Whether used for motor leads in new energy vehicles or control lines in rail transit, this combination of rigidity and flexibility ensures cable safety and reliability in applications with high vibration and high bending.

Volsun offers a wide range of fiberglass sleeving options, ranging from Φ2.0mm to Φ25.0mm, and can customize wall thickness based on voltage levels. A wide range of colors is also available, including eight common colors such as white, black, and red, ensuring both functional differentiation and aesthetic appeal. All materials comply with RoHS and REACH environmental standards, making them suitable for use in automotive and military applications, where hazardous substances are strictly restricted.

Currently, the NS-GF200RUB-D fiberglass sleeve has been widely used in a variety of high-reliability applications, including new energy vehicle battery cables, rail transit control systems, and military instrument wiring harnesses. Choosing an insulating protective sleeve that resists cracking, brittleness, aging, and failure under extreme conditions such as high temperature, severe cold, and vibration is essential for the long-term operation of your equipment.
