In highly integrated equipment such as new energy vehicles and rail transit, circuit wiring often faces the challenges of confined spaces and complex layouts, making traditional sleeving difficult to adapt. To address this challenge, Volsun has launched the NS-GF200RUB-8.0 Expandable Silicone Rubber Fiberglass Sleeving. With its innovative "alkali-free glass fiber + silicone rubber coating" structure, it boasts an expansion capacity of ≥100% and high-temperature resistance up to 200°C. It easily handles various complex wiring scenarios, providing a reliable, expandable, extreme-resistant, and highly insulating barrier for high-voltage circuits.

The NS-GF200RUB-8.0 fiberglass sleeving boasts an expansion rate exceeding 100%, an inner diameter range of Φ2.0 to Φ25.0mm, and flexible expansion, easily accommodating special-shaped connectors or multi-strand wire harnesses. Repetitive cutting and cutting are eliminated during installation, significantly improving assembly efficiency. Its flexible yet strong material, combined with glass fiber and silicone rubber coating, prevents cracking or delamination when bent, perfectly conforming to the complex wiring curves within the device.

It also excels in temperature resistance. It can operate stably in temperatures ranging from -40°C to 200°C. Even after being exposed to 180°C for 48 hours, it remains intact after being bent. It can withstand the high temperatures of new energy vehicle battery compartments and outdoor equipment in extremely cold regions. Furthermore, its insulation resistance reaches up to 100GΩ, with an initial breakdown voltage of at least 8.0kV, which remains above 6.0kV after expansion, effectively isolating high-voltage circuits and eliminating potential leakage hazards.

Expandable fiberglass sleeving complies with authoritative standards such as RoHS, REACH, and UL, and its volatile matter content is controlled to less than 1.5%, meeting the stringent environmental requirements of the automotive and military industries. In addition, it supports customization in eight basic colors, including transparent, black, and red. Flame retardancy and heat resistance can also be adjusted as needed, meeting the dual needs of equipment identification and functional protection.

This kind of fiberglass sleeving is widely used in various scenarios and precisely meets the needs of multiple industries. For example:

New Energy Vehicles: Φ8.0-Φ13.0mm specifications are suitable for insulating battery cables and motor leads. Its high expansion and high-temperature resistance perfectly meet automotive standards.

Rail Transit: Φ14.0-Φ25.0mm specifications are suitable for train control system wiring. Its low-temperature resistance and high insulation performance safeguard outdoor high-voltage circuits.

Military and Aerospace: Φ2.0-Φ7.0mm specifications provide protection for the internal cables of precision instruments. Low volatile matter and customizable colors ensure stable operation in confined spaces.

Special Vehicles: Φ8.0-Φ10.0mm specifications provide flexible protection for engineering vehicle power cables. Customizable flame retardancy further enhances operational safety.
