| Quantity: | |
|---|---|
| Material | Conductivity | Density | Key Advantages | Typical Use |
|---|---|---|---|---|
| Hard Drawn Copper | 97% IACS | 8.89 g/cm³ | Highest conductivity, excellent short-circuit performance | High-conductivity lines, grounding, railway catenary |
| Hard Drawn Aluminium (1350/1370) | 61% IACS | 2.70 g/cm³ | Lightweight, lower cost, good corrosion resistance | Overhead distribution, long spans where weight is critical |
Selection logic: Choose copper when conductivity and short-circuit withstand are priorities. Choose aluminium when weight reduction, cost savings, and corrosion resistance matter more. For copper-aluminium transition points, use bimetal connectors to avoid galvanic corrosion.
Cross-section range: 16 – 1500 mm² (4 AWG – 3000 kcmil).
Stranding: 7, 19, 37, 61, 91, 127 wires. Higher strand counts improve flexibility but may slightly reduce tensile strength for a given cross-section.
Class: Class AA concentric-lay stranding is standard for bare overhead conductors.
Determine size by load current, voltage drop, short-circuit current, and mechanical loading (wind, ice).
Voltage: Hard drawn bare conductors are used in overhead lines from distribution voltages up to EHV transmission levels. Corona performance improves with larger conductor diameter.
Ampacity: Depends on conductor size, material, ambient temperature, wind speed, solar radiation, and permissible conductor temperature. Confirm the continuous current rating and short-circuit withstand for the project.
Tensile strength: Hard drawn copper provides higher tensile strength than annealed copper. Aluminium 1350-H19 offers moderate strength.
Span design: Calculate sag and tension under worst-case wind and ice loading. Maximum allowable tension is typically 20–25% of ultimate tensile strength.
Long spans: For river crossings, valleys, or extra-long spans, consider ACSR or high-strength conductors.
Coastal and industrial areas: Specify optional coating or grease infusion for corrosion protection.
High-pollution zones: Confirm creepage and corrosion requirements.
High-temperature areas: Verify conductor temperature limits against ambient conditions.
Vibration-prone spans: Consider vibration dampers or spiral vibration rods.
Bare surface: Standard for clean environments.
Grease-coated: For corrosion protection in coastal or industrial areas.
Oxidized: For specific bonding or appearance requirements.
Custom stranding: Different wire diameters, lay lengths, or material combinations available upon request.
Custom packaging: Coils, wooden drums, steel drums, or steel-wooden drums.
Specify applicable standards:
ASTM B232: Concentric-lay-stranded aluminium conductors, coated-steel reinforced (ACSR) – and related bare conductor specifications.
IEC 61089: Round wire concentric lay overhead electrical stranded conductors.
BS 215: Aluminium conductors and aluminium conductors, steel-reinforced.

This metal-oxide surge arrester (MO arrester) is a gapless zinc oxide varistor device designed to protect power system equipment from overvoltages caused by lightning strikes and switching operations. It is suitable for transformers, switchgear, cable terminations, motors, and overhead lines in distribution and transmission networks. The arrester is available in polymer-housed or porcelain-housed versions, with rated voltages from 0.22 kV to 500 kV and nominal discharge currents of 5 kA, 10 kA, or 20 kA. For procurement, the key value is fast response, maintenance-free operation, and compliance with IEC 60099-4, ensuring reliable insulation coordination and reduced equipment failure risk.
Select the arrester MCOV according to the system grounding type. Published MCOV ratings are typically based on 40°C or 45°C ambient temperature.
MCOV should be at least 5% higher than the highest continuous voltage of the power system. Rated voltage is generally 1.25 × MCOV.
IEC 60099-4:2014 classifies surge arresters into station (S) and distribution (D) classes by energy handling capability, subdivided into high duty (H), medium duty (M), and low duty (L). IEEE C62.11 further defines application types:
5 kA: Standard distribution protection, moderate lightning activity.
10 kA: Substations, critical transformers, areas with high lightning density. Recommended for most MV/HV applications.
20 kA: Very high lightning exposure or critical station equipment.
Energy absorption capability determines the arrester's ability to survive multiple lightning strokes or prolonged switching surge events. Line discharge classes (per IEC 60099-4) include Class 1 (2 kJ/kV), Class 2 (5.5 kJ/kV), Class 3 (6.0 kJ/kV), and higher. Select a class that matches the expected energy duty of the installation.
Choose polymer when weight, safety, and pollution performance are priorities. Choose porcelain when extreme mechanical load and long-term UV stability are critical.
Select creepage distance according to the installation environment per IEC 60815:
| Pollution Level | Minimum Creepage | Typical Application |
|---|---|---|
| Light (Level I) | 16 mm/kV | Indoor, clean areas |
| Medium (Level II) | 20 mm/kV | General outdoor |
| Heavy (Level III) | 25 mm/kV | Coastal, industrial |
| Very Heavy (Level IV) | 31 mm/kV | Severe coastal, desert, industrial pollution |
Standard silicone rubber housings are designed with a minimum specific creepage distance of 31 mm/kV, meeting Category IV (very heavy) pollution level.
Indoor switchgear: Compact designs with appropriate clearance. Verify altitude and ambient temperature derating.
Outdoor substations: Confirm creepage distance for pollution level and mechanical load from wind/ice.
Coastal/desert: Specify polymer housing with high creepage distance and hydrophobic surface.
High-altitude: Derate for altitudes above 1,000 m.
Seismic zones: Verify mechanical strength and mounting requirements.
Specify applicable standards:
IEC 60099-4: Metal-oxide surge arresters without gaps for AC systems.
IEEE C62.11: Metal-oxide surge arresters for AC power circuits.
IEC 60099-5: Selection and application recommendations.
Routine tests include AC withstand, partial discharge, and critical voltage measurement. Type tests may include operating duty, residual voltage, and short-circuit tests.

The 12kV Metal Oxide Surge Arrester is a high performance lightning protection device with superior protection performance, light weight, pollution resistance, and stable performance.
It utilizes the excellent non linear volt ampere characteristics of zinc oxide (ZnO). Under normal working voltage, the current flowing through the surge arrester is very small (microamp or milliampere level). When an overvoltage occurs, the resistance drops sharply, venting the overvoltage energy to achieve effective protection.
Unlike traditional lightning arresters, this metal oxide surge arrester has no discharge gap — it relies solely on the non linear characteristics of zinc oxide for discharge and interruption.

Polymeric Metal Oxide Arrester for Protect Electrical Equipment
Zinc oxide surge arrester is a lightning protection device with superior protection performance, light weight, pollution resistance and stable performance. It mainly uses the good non-linear volt-ampere characteristics of zinc oxide to make the current flowing through the surge arrester at normal working voltage very small (microamp or milliampere level); when the overvoltage acts, the resistance drops sharply, venting the overvoltage Energy to achieve the effect of protection. The difference between this kind of lightning arrester and the traditional lightning arrester is that it has no discharge gap, and uses the non-linear characteristics of zinc oxide to discharge and break.

Metal oxide Zinc High Voltage Surge Arrester for Overhead Line
Zinc oxide surge arrester is a lightning protection device with superior protection performance, light weight, pollution resistance and stable performance. It mainly uses the good non-linear volt-ampere characteristics of zinc oxide to make the current flowing through the surge arrester at normal working voltage very small (microamp or milliampere level); when the overvoltage acts, the resistance drops sharply, venting the overvoltage Energy to achieve the effect of protection. The difference between this kind of lightning arrester and the traditional lightning arrester is that it has no discharge gap, and uses the non-linear characteristics of zinc oxide to discharge and break.
