Reliable High-Performance Fire-Retardant FRP Round Tube for Electrical Insulation
Hengshui Ruibin New Materials LLC, a professional manufacturer established in 2019, presents this premium fire-retardant FRP round tube with a 120mm outer diameter and 8mm wall thickness. Designed specifically for demanding electrical insulation applications, this tube combines rigorous fire safety performance with exceptional thermal stability, offering a heat deflection temperature of up to 220°C. Whether you are constructing busbar supports, transformer components, or structural insulating frames, this product delivers dependable mechanical strength and long-term electrical reliability.
Product Highlights and Technical Advantages
- Fire-Retardant Composition: Engineered with flame-resistant resin systems, the tube meets stringent fire safety requirements, reducing the risk of flame propagation and smoke generation in critical electrical installations.
- Superior Heat Deflection Resistance: With a heat deflection temperature rated at 220°C, this tube maintains its shape and structural integrity even under sustained elevated temperatures, ensuring reliable performance in high-temperature environments.
- Excellent Electrical Insulation: The fiberglass-reinforced polymer matrix provides high dielectric strength and low thermal conductivity, making it an ideal choice for insulating components in switchgear, motors, and transformers.
- High Mechanical Strength: The 8mm wall thickness contributes to outstanding compressive and impact resistance. The tube can withstand heavy mechanical loads without deformation, suitable for structural and support applications.
- Corrosion and Moisture Resistance: The FRP material is inherently resistant to moisture, chemicals, and UV degradation, ensuring long service life even in harsh operating environments.
- Lightweight and Easy to Machine: Compared to metal alternatives, this FRP tube is significantly lighter, simplifying handling, installation, and fabrication. It can be easily cut, drilled, or machined to meet custom requirements.

Frequently Asked Questions
Q1: What makes this FRP tube fire-retardant?
A1: The tube is manufactured using specially formulated flame-retardant resin systems combined with fiberglass reinforcement. This composition helps prevent the spread of flames and reduces smoke generation when exposed to fire sources, enhancing overall installation safety.
Q2: Can this tube be used in continuous high-temperature environments?
A2: Yes, the 220°C heat deflection temperature indicates the tube can withstand high operating temperatures without significant deformation. However, actual performance depends on specific application conditions such as mechanical loading. Our engineers can provide guidance for your exact use case.
Q3: Do you provide custom lengths or cut-to-size services?
A3: Absolutely. We offer standard 6-meter lengths, and cutting services are available upon request. Custom lengths are manufactured to meet your project specifications and minimize on-site waste.
Q4: Is the tube suitable for outdoor applications?
A4: Yes, the FRP material exhibits strong resistance to moisture, UV radiation, and corrosion, making it suitable for both indoor and outdoor installations. Colorants and UV-stabilized resin options are also available for enhanced weather resistance.
Q5: What are the main differences between FRP tubes and metal tubes for electrical use?
A5: FRP tubes offer natural electrical insulation, lower weight, excellent corrosion resistance, and no risk of induced eddy currents, making them ideal where non-conductive and heat-resistant materials are required. Metal tubes require additional insulation layers and are heavier, which can complicate installation.
Q6: Can I request samples before placing a bulk order?
A6: Yes, sample orders are welcomed. We can produce samples based on your specifications, and sample evaluation is an effective first step before full production.
Q7: What is the lead time for large orders?
A7: Lead time varies depending on the order quantity and customization level. Generally, standard orders can be completed within 2-3 weeks after confirmation. We will provide an accurate delivery schedule upon inquiry.
Q8: How do you ensure consistent quality across production batches?
A8: Our manufacturing process includes strict incoming material inspection, in-process quality checks, and final performance testing. We monitor dimensions, surface quality, fire performance, and thermal properties to deliver consistent and reliable products.
