Pericline Insulators: Advanced Reliability for 33 kV Distribution Networks
Overview
Pericline Insulators are meticulously engineered to provide superior dielectric strength and mechanical stability for critical medium voltage applications up to 33 kV. Designed for the demanding environments of power distribution, these insulators ensure the reliable and safe operation of overhead lines, substations, and industrial installations. Whether you require robust porcelain for traditional systems or advanced polymer for challenging conditions, Pericline offers a high-performance solution that minimizes downtime and optimizes operational efficiency.
Key Features
High Dielectric Strength: Exceptionally high insulation levels prevent current leakage and flashovers, even under severe voltage fluctuations and transient surges.
Exceptional Mechanical Performance: Engineered to withstand high tensile, compressive, and cantilever loads, providing robust support for conductors and equipment in all weather conditions.
Superior Environmental Resistance: Available in materials designed to resist UV radiation, extreme temperatures, ice loading, salt fog, industrial pollution, and acidic rain, ensuring long-term performance and durability.
Optimized Creepage Distance: Precisely designed shed profiles and creepage distances prevent surface discharge and reduce the risk of flashover in contaminated environments.
Robust Material Options:
High-Grade Electrical Porcelain: Offers inherent rigidity, excellent thermal stability, and proven long-term performance in diverse climates.
Hydrophobic Silicone Rubber (Polymer): Provides superior self-cleaning properties, reduced weight, non-brittle characteristics, and enhanced arc resistance.
Corrosion-Resistant Hardware: End fittings and caps are manufactured from hot-dip galvanized steel or durable alloys, ensuring longevity and resistance to rust and degradation.
Compliance with International Standards: Manufactured and tested in accordance with leading international standards such as IEC 60383, IEC 60120, ANSI C29.2, and ANSI C29.7, guaranteeing quality and interoperability.
Optimized Design: Compact and lightweight designs (especially polymer variants) facilitate easier handling, transport, and installation, reducing labor costs and time.
