As a leading porcelain insulator manufacturer China, Hebei Yipeng Powerline specializes in high-quality wet-process porcelain insulators for transmission, distribution, and substation applications. Our wholesale porcelain insulators supplier China factory produces porcelain pin type insulators, porcelain suspension disc insulators, porcelain line post insulators, porcelain stay strain insulators, porcelain spool insulators, and porcelain station post insulators – all fully compliant with ANSI C29 porcelain insulators and IEC 60273 / IEC 60383 suspension porcelain insulators standards.

Applications

As a professional porcelain insulator manufacturer China based, we provide a complete portfolio covering transmission lines, distribution networks, substations, transformers and low voltage systems.

• Porcelain suspension insulators for distribution and transmission lines, widely used as high voltage porcelain insulators from 10kV porcelain insulators up to 500kV porcelain insulators for overhead lines.

• Porcelain pin insulators 11kV 33kV, also for 6kV, 10kV, 15kV, 22kV, 24kV, 25kV and 35kV distribution lines, suitable for wooden, concrete and steel poles.

• Porcelain line post insulators for substations and line applications, providing non‑puncture design and high mechanical failing load, ideal for 11kV, 22kV, 33kV, 66kV, 110kV and 132kV systems.

• Porcelain stay insulators (egg insulators) for guy wires and stay wires in distribution lines such as 11kV and 33kV networks, improving safety for poles and structures.

• Porcelain bushing insulators for transformers, switchgear and GIS equipment, including hollow core porcelain bushings and transformer through‑wall bushings.

• LV porcelain insulators for low voltage lines, commonly used around 400V for pole line hardware and other electrical fittings.

Whether you need standard types or custom porcelain insulator China designs, we can supply IEC certified porcelain insulators and ANSI porcelain insulators optimized for your specific project and local standards.Contact us.

Porcelain Insulator Selection Guide

Selecting the right porcelain insulator is critical for safe and reliable operation of your overhead lines and substation equipment. Our porcelain insulator selection guide helps you choose suitable models quickly:

• System voltage & application

  Define the rated voltage and application: 10kV porcelain insulators or 11kV porcelain insulators for distribution lines, 22kV / 24kV / 25kV porcelain insulators and 33kV porcelain insulators for medium voltage networks, 66kV, 110kV, 132kV, 220kV, 330kV and 500kV porcelain insulators for high voltage transmission lines and substations.

• Insulation performance

  Check creepage distance and dry arcing distance according to IEC 60383 and IEC/TS 60815, especially in polluted or coastal areas.

• Mechanical requirements

  Confirm specified mechanical load (SML), bending strength or tensile strength (kN) according to your line design and relevant ANSI C29 or GB/T requirements.

• Installation and hardware

  Match porcelain suspension insulators, porcelain pin insulators, porcelain line post insulators, porcelain stay insulators or porcelain bushing insulators with your existing fittings, cross arms and clamps.

If you need more details, we can provide a porcelain insulator datasheet, basic porcelain insulator selection guide and porcelain insulator price list based on your technical specification and bill of materials.
