Key Features & Construction
Insulation System
Multi-disc silicone housing: The light grey, ribbed porcelain insulator provides mechanical strength and arc resistance. The 360mm creepage path (achieved through optimized shed design) minimizes surface leakage currents, critical for coastal or industrial areas.
Corona rings (grading rings): The flared ribs at the base equalize electric field distribution, suppressing corona discharge and partial discharges at rated voltage.
Surge Protection Core
Metal Oxide Varistor (MOV) stack: Zinc oxide (ZnO) discs inside the housing offer nonlinear resistance, clamping overvoltages to safe levels (e.g., <35kV for 10kA impulse).
Hermetic sealing: epoxy-sealed construction prevents moisture ingress, ensuring long-term stability.
Termination & Grounding
Top terminal: Bolt-and-nut connection (visible in image) for secure line conductor attachment, compatible with busbars or overhead lines.
Braided copper ground strap: Low-impedance path (typically ≤10Ω) for surge current dissipation, solder-bonded to the arrester base for durability.
Mechanical Robustness
Pedestal base: Reinforced polymer/ceramic support withstands wind loads and seismic forces (tested per IEC 61463).
Anti-fracture design: Porcelain housing includes fracture-safe features to prevent shattering during faults.
Typical Applications
Substations: Protects transformers, circuit breakers, and switchgear from lightning/switching surges.
Industrial plants: Safeguards sensitive equipment in mining, oil/gas, or manufacturing facilities.
Renewable energy: Used in solar/wind farm collector systems.
Compliance & Testing
Standards: IEC 60099-4, IEEE C62.11, ANSI C62.1
Tests:
Power frequency withstand: 30kV/1min (dry)
Impulse withstand: 75kV (1.2/50μs)
Leakage current: <1mA at Uc
Advantages Over Competitors
360mm creepage: Superior pollution performance (Class IV per IEC 60815).
Visible grounding: Braided strap allows easy inspection (vs. hidden connections).
Modular design: Facilitates replacement without disassembling adjacent equipment.
For installation, ensure vertical mounting (as shown) with a clear air gap to grounded structures. Periodic infrared inspection of terminals and leakage current monitoring are recommended.
