Born for Superior Performance – Your High-Quality Fiberglass Wound Tube Solution for Instrument Transformers

We have learned of your search for high-performance, highly reliable insulation component solutions for instrument transformers. It is our great honor to introduce our core product: professionally designed and manufactured epoxy fiberglass wound tubes specifically for instrument transformers. We firmly believe this product can perfectly meet your stringent requirements for electrical performance, mechanical strength, and long-term stability.

Why Our Fiberglass Wound Tubes Are the Ideal Choice for Instrument Transformers?

1. Unparalleled Electrical Insulation Performance

   · The product is formed using high-purity alkali-free glass fibers and a premium epoxy resin system via computer-controlled precision filament winding technology.

   · It possesses extremely high dielectric strength and excellent arc resistance, effectively withstanding the high-voltage electric fields present during transformer operation to ensure absolute insulation safety. It is the ideal material for insulating cores and bushings in high-voltage and ultra-high-voltage instrument transformers.

2. Exceptional Mechanical and Structural Strength

   · The unique wound structure grants the product exceptional axial and radial strength, with outstanding resistance to bending and impact.

   · It offers excellent dimensional stability. A low coefficient of thermal expansion ensures the maintenance of shape and size across a wide temperature range (-50°C to +150°C), effectively preventing internal stress cracks caused by thermal cycling and safeguarding the long-term accuracy of the transformer.

3. Superior Environmental Adaptability

   · The product inherently features excellent moisture resistance and chemical corrosion resistance.

   · We can provide solutions with weather-resistant silicone rubber coating or the addition of hydrophobic sheds, enabling it to handle harsh outdoor environments (UV, rain, snow, pollution) with ease, significantly enhancing the operational lifespan and reliability of outdoor instrument transformers.

4. Tailored Design and Service

   · We are not a standard parts supplier. We specialize in custom manufacturing based on your drawings, allowing flexible adjustments to the tube's inner diameter, outer diameter, length, wall thickness, threading, grooving, and mounting interfaces according to your specific transformer design.

   · Whether for oil-immersed, SF6 gas-insulated, or dry-type instrument transformers, we can provide the most suitable material and process solutions (e.g., GPO-3, FRP, specific flame-retardant/temperature-resistant grades).

Our Core Advantages:

· Focus and Expertise: We have been deeply engaged in the field of electrical insulating composites for [Please fill in specific number, e.g., over ten years], with a particular focus on the transformer and instrument transformer industry. We have a profound understanding of your technical challenges.

· Full-Process Control: From raw material selection and precision winding to curing and final inspection, we maintain strict control over the entire process within our own factory, ensuring consistent quality in every single product.

· Comprehensive Test Reports: We can provide a full set of third-party test reports including dielectric strength, flexural strength, water absorption, flame retardancy rating (UL94 V-0), and more, giving you complete peace of mind in your procurement.

We sincerely hope for the opportunity to engage in further discussions with your company. If you can provide specific technical drawings or performance requirements, our engineering team will promptly conduct a feasibility analysis and provide samples for your evaluation.

We look forward to your inquiry and to working together to build safer, more reliable power equipment.
