The iron parts on substation insulators are usually made of aluminum alloy.
Material selection basis
Aluminum alloy has characteristics such as light weight, good electrical conductivity, and strong corrosion resistance, making it suitable for power equipment scenarios that require both mechanical strength and insulation performance.
Comparison with other metal materials
Cast iron: high density, prone to rust, not suitable for outdoor substation environments.
Zinc-aluminum alloy: good strength and corrosion resistance, but higher cost.
Practical application scenarios
Aluminum alloy iron parts are mainly used to support and fix insulators, and must meet the requirements for long-term exposure to harsh weather conditions.
