About Shaanxi Taporel Electrical Insulation Technology Co., Ltd.

Founded in December 1995, Shaanxi Taporel Electrical Insulation Technology Co., Ltd. is a high-tech enterprise specializing in the R&D, manufacturing, and global sales of electrical insulation and fiber-reinforced plastic (FRP) composite materials. Located in the Xi’an Jinghe Industrial Park, our facility spans 73,332 m² (110 acres) with a total construction area of 98,000 m².

Core Products & Brand Influence

Under our registered brand 【Taporel】, we offer over 20 types of high-performance products, including:

  • Insulating Rods: Epoxy rods (round, square, and custom profiles), VPI pultruded core rods.
  • Insulating Tubes: Epoxy filament wound tubes/cylinders (cloth/filament), Pultruded & Wound tubes, PD-free (Partial Discharge-free) tubes, and foam-filled tubes.
  • Hollow Composites: Hollow composite insulator bushings.
  • Specialized Components: Spacers and slats for dry-type transformers and reactors, SMC, and BMC molded products.

Taporel products cover voltage levels from 10kV to 1100kV. Our materials are extensively utilized in China’s UHV (Ultra-High Voltage) and EHV (Extra-High Voltage) power grids and are the preferred choice for manufacturers of composite suspension, pin, post, and station insulators, as well as surge arresters and cable accessories. Since 2005, we have exported to over 30 countries worldwide.

Production Scale & World-Class Testing

Taporel operates as China’s largest manufacturer of pultruded core rods and a leading producer of filament wound cylinders. Our infrastructure includes:

  • 100 Pultrusion Lines: Daily capacity of 20,000 kg (calculated at Φ18 core rods).
  • High-Voltage Testing Hall: A massive 24m x 24m x 20m facility equipped with 600kV, 300kV, and 200kV power frequency withstand devices.
  • Advanced R&D Equipment: 900kV impulse voltage generator, Partial Discharge (PD) testers, 500kN tensile strength machines, and stress-corrosion testing systems.

Innovation, Patents & Certifications

As a national high-tech enterprise and recipient of the National Science and Technology Progress Award, Taporel holds nearly 10 invention patents, including:

  • Release Agent-Free Core Rods: (Patent No. 200610041850.1) — The only core rod in China to pass type tests at the KEMA Laboratories (Netherlands).
  • PD-Free Filament Wound Tubes: (Patent No. ZL 2010 1 0109659.2).

Our commitment to quality is backed by rigorous international testing, including the 5000-hour stress corrosion test (Wuhan HV Research Institute), 1 million vibration cycles, and the ASTM 100-hour boiling test. In 2024, we achieved Green Factory Certification, Carbon Footprint Certification, and Intelligent Manufacturing Management System Certification.

Taporel is a lead drafter of China’s national standards (GB/T 2300-2008) and UHV composite insulator core rod standards. We strictly implement ISO 9001, ISO 14001, and ISO 45001 management systems.
