PS-35 Porcelain Line Post Insulator
The PS-35 porcelain line post insulator is designed to provide electrical insulation and mechanical support for conductors installed on outdoor overhead power lines. Its multi-shed porcelain profile increases the surface leakage path and helps maintain insulation performance under outdoor service conditions.
The product is selected according to the system voltage, required creepage distance, mechanical load, conductor arrangement, mounting dimensions and local environmental conditions. Final dimensions and electrical or mechanical ratings must be confirmed against the approved product drawing and project specification.
Key Features
• Electrical porcelain insulating body
• Multi-shed profile for outdoor insulation
• Smooth glazed surface for easier cleaning and reduced moisture retention
• Metal fitting and threaded connection for line-hardware assembly
• Suitable for drawing-based and project-specific supply
• Dimensions, fittings and performance ratings confirmed before production

Material and Surface Treatment
The insulating body is made from glazed electrical porcelain. The glazed surface provides a smooth, durable exterior suitable for outdoor electrical insulation applications.
Metal fittings and threaded hardware are supplied with the corrosion-protection treatment specified in the approved drawing or purchase specification. The exact steel grade, galvanizing method and coating requirement must be confirmed for each order before they are stated in the final technical data sheet.
Applications
The PS-35 porcelain line post insulator can be selected for:
• Outdoor overhead distribution lines
• Conductor insulation and mechanical support
• Pole and crossarm-mounted line structures
• New distribution-line construction
• Rural electrification projects
• Maintenance and replacement of compatible line insulators
Product suitability depends on the actual system voltage, conductor arrangement, mechanical loading, pollution severity, altitude and installation dimensions. It should not be selected solely by model name or appearance.
Applicable Standards
Where specified by the purchaser and supported by the corresponding design and test documentation, the product may be manufactured and inspected with reference to applicable requirements of IEC 60383-1 for ceramic or glass insulators used on overhead lines above 1,000 V.
Compliance with a specific standard applies only after the exact product configuration, test requirements and supporting documentation have been confirmed. The model should not be presented as “IEC certified” without a corresponding test report.
Quality Control
Inspection requirements can include:
• Dimensional and visual inspection
• Porcelain and glaze surface inspection
• Metal-fitting and threaded-connection inspection
• Mechanical testing according to the agreed specification
• Electrical testing according to the agreed specification
• Packaging and marking inspection
The applicable inspection plan and acceptance criteria are confirmed according to the product drawing, purchase specification and order requirements.
Information Required for Selection
To recommend or manufacture the correct configuration, please provide:
• System voltage
• Required creepage distance
• Mechanical or cantilever load
• Installation drawing
• Mounting and connection dimensions
• Environmental and pollution conditions
• Required standard and test documents
• Order quantity and packaging requirements
Customization
Dimensions, metal fittings, glaze color, creepage requirements, marking and packaging can be evaluated according to approved drawings and order quantities.
