The 11KV Polymer Lightning Arrester fills the gap of slow surge response in traditional arresters, with a nanosecond-level clamping speed to protect 11kV overhead distribution lines (up to 35kV systems). It uses a ZnO varistor core (10kA nominal discharge current, 8/20μs) and four grey polymer sheds (285mm creepage distance), with a maximum continuous operating voltage (MCOV) of 9.40kV. It diverts lightning/switching surges away from transformers, reclosers, and insulators— critical for reducing downtime in rural/suburban grids.
Nonlinear Voltage-Current Behavior: Acts as an insulator under normal voltage (<11kV) and conducts instantly during surges, clamping residual voltage to <35kV.
100kA High-Current Withstand: Handles 100kA (4/10μs) high currents, suitable for high-lightning-frequency areas (e.g., plains, coastal regions).
IP67-rated housing prevents moisture ingress, while UV-resistant polymer withstands -40°C to +85°C thermal cycling— no performance degradation in extreme temperatures.
Installed near rural transformers, it diverts lightning surges, cutting transformer failure rates by 50% vs. unprotected setups.
Mounted at substation feeders, it stops surges from reaching expensive switchgear/transformers, avoiding costly repairs.
Protects step-up transformers and inverters in lightning-prone wind/solar farms, ensuring uninterrupted power generation.
Global Standards Compliance: Designed to IEC 60099-4/IEEE C62.11; provides certification documents for surge performance.
Site-Specific Surge Analysis: Offers lightning frequency assessments to recommend optimal installation positions (e.g., line taps, canyon crossings).
After-Sales Assurance: 6-year warranty + on-site grounding guidance; replaces defective units within 48 hours of notification.
