XWP2 Double-Shed Anti-Pollution Porcelain Disc Insulator
The XWP2 double-shed anti-pollution porcelain disc insulator is designed for use in suspension and tension insulator strings on outdoor overhead power transmission and distribution lines. It provides electrical insulation and mechanical connection between energized conductors and supporting structures.
Its double-shed porcelain profile is designed to provide an extended creepage path and support improved performance in environments affected by dust, salt, industrial contamination or other airborne pollutants. The required creepage distance and number of insulator units must be selected according to the system voltage, pollution severity, site altitude and insulation-coordination requirements.
Key Features
- Double-shed profile designed for pollution-prone outdoor environments
- High-strength electrical porcelain insulating body
- Glazed surface for stable outdoor performance and easier cleaning
- Suitable for suspension and tension insulator-string assemblies
- Metal coupling components selected according to the required XWP2 submodel
- Available with customized dimensions, coupling sizes, markings and packaging
Materials and Construction
The main insulating component is manufactured from electrical porcelain with a glazed surface. Metal coupling fittings and the cementing system are supplied according to the approved product drawing and customer specification. Metal material, protective coating, coupling designation and assembly dimensions must be confirmed before production.
Available Model Selection
XWP2 identifies a product series rather than one fixed specification. Different submodels may have different electromechanical failing loads, unit spacing, disc diameters, creepage distances, coupling sizes and electrical characteristics. The complete model suffix must therefore be confirmed before quotation or order placement.
Typical Applications
- Overhead power transmission lines
- Overhead distribution lines
- Suspension insulator strings
- Tension and dead-end insulator strings
- Coastal, dusty and industrial environments after pollution-level assessment
- Utility, substation and infrastructure projects requiring porcelain string insulators
Reference Standard
The product can be manufactured and inspected with reference to IEC 60383-1 when specified in the purchase contract. Final compliance, inspection items and acceptance criteria are determined by the confirmed model, approved drawing, applicable project standard and agreed test documentation.
Quality and Inspection
- Porcelain and glaze appearance inspection
- Dimensional and coupling verification
- Mechanical and electrical testing according to the agreed standard
- Assembly and workmanship inspection
- Marking, packaging and traceability verification
Information Required for Selection
To recommend the correct XWP2 model, please provide the system voltage, required electromechanical failing load, creepage-distance requirement, pollution severity, coupling size, string arrangement, installation altitude, applicable standard and project drawing.
