The main products include epoxy insulation rods (round, square, and special-shaped), vacuum-injected composite insulator core rods, insulation tubes, epoxy tubes, epoxy glass filament wound tubes(cylinders), epoxy glass cloth wound tubes(cylinders), melamine glass cloth tube, epoxy pultruded & wound tubes, on-line braided insulating tubes, partial discharge-free insulating tubes, foam-filled tubes, hollow composite insulator sleeves, insulating support strips for dry-type transformers, insulating strips for dry-type reactors, insulating slats for dry-type reactors, and SMC and BMC products specifically designed for the electrical industry—more than twenty types of products in total.Our products are widely used in the manufacturing industry of electrical insulation equipment. Registered Trademark: Taporel®.It is the preferred supplier for manufacturers of composite suspension insulators, composite pin insulators, composite post insulators, hollow composite insulators, composite cross-arms, drop-out fuses, high-voltage disconnecting switches, composite insulators specially designed for electrified railways , spacer dampers, composite housed zinc oxide surge arresters, high-voltage fuses, dry-type transformers, reactors, cable accessories and other products.Nowadays, our products cover a wide range of voltage levels from 10 kV to 1,100 kV. In particular, they have been widely and extensively applied on ultra-high voltage (UHV) and extra-high voltage (EHV) transmission lines of China’s power grid, and have earned recognition from experts and composite insulator manufacturers. Since 2005, our composite insulator core rods have been exported to more than 30 overseas countries, with products sold all over the world.
Taporel currently employs 150 staff including 32 researchers and management personnel. Equipped with 100 professional pultrusion production lines, we deliver a daily output of approximately 20,000 kg of 18-diameter composite insulator core rods, alongside 5 sets of dedicated production equipment for arrester epoxy tubes. We own a full range of professional testing facilities, covering a 24m×24m×20m high-voltage testing hall, complete power frequency withstand voltage, impulse, partial discharge, tensile, physical and chemical, water diffusion and stress corrosion resistance testing equipment. As China’s largest manufacturer of pultruded composite insulator core rods, we are also a leading supplier of fiberglass filament-wound insulating tubes and custom pultruded profiles.
We adopt standardized, scientific and rigorous management systems and hold High-tech Enterprise qualification, as well as the National Science and Technology Progress Award. The company owns nearly 10 authorized national invention patents, including the Agent-Free Composite Insulator Core Rod and Partial Discharge-Free Composite Glass Fiber Wound Tube. Our brand “Taporel” is recognized as Shaanxi Famous Brand and Xi’an Famous Brand.
The company strictly complies with ISO 9001, GB/T 28001 and ISO 14001 management systems. In 2024, we obtained multiple green and smart manufacturing certifications, including Green Factory, Green Enterprise, Green Supply Chain, Product Carbon Footprint and Green Design Product certifications. We implement a strict three-level inspection system throughout production. All products fully comply with IEC and national industry standards, with every core rod and insulating tube undergoing one-by-one withstand voltage and partial discharge testing before delivery.
Rooted in China and global-oriented, we actively engage in international high-voltage insulation technology exchanges and cooperation. Supported by reliable credibility and advanced technology, we have gained wide trust from global partners, laying a solid foundation for international market expansion.
