Import 27kv Epoxy Resin Insulators — Buy in wholesale FOB from Supplier in China

These 27KV epoxy resin insulators are manufactured using APG (Automatic Pressure Gelation) technology, a process that ensures uniform density and eliminates internal voids through controlled pressure and temperature curing. The insulators comply with IEC 60273-1990 for post insulators rated above 1000V, with a working voltage range covering 12kV, 15kV, 17.5kV, 24kV and 36kV. The standard colour is RAL 8016, though custom colours are available on request, and the operating temperature range spans from -20°C to +75°C.

The material composition includes premium epoxy resin, hardener and silicone powder, mixed in a three-speed process under vacuum to remove bubbles, which enhances dielectric strength and mechanical integrity. The molds are precisely developed to meet the solidifying and curing time requirements, ensuring consistency in dimensions and performance. Typical industry specifications for such insulators include a dielectric strength of 20 kV/mm, a tensile strength of 50 MPa and a tracking resistance of 600V, though these values should be confirmed with the supplier for this specific model.

These insulators are used in medium-voltage electrical distribution systems, switchgear, and transformer stations where reliable insulation and mechanical support are critical. Buyers typically include electrical utilities, industrial plants and OEMs of power equipment. The product is packed in cartons on plastic pallets, with popular models available from stock. For custom designs, a one-month lead time is required for mold development, and OEM branding or date stamps can be applied upon request.

Yueqing Top Electric Science Co., Ltd. is based in Top Industrial Park, Wenzhou, Zhejiang, China, with a focus on electrical insulation solutions. The company specialises in APG technology for epoxy insulators, offering a process that combines precision mold development with strict adherence to production timelines for solidifying and curing.
