What type of bolts are used in high-voltage distribution boxes
"Galvanised steel bolts are normally used but brass or bronze bolts have been used because their coefficients of expansion closely match the copper conductor and hence the contact pressure does not vary widely with operating temperature. Victory Fasteners supplies a comprehensive range of high-performance bolts, industrial fasteners, and bespoke custom fixing solutions specifically engineered for the electricity distribution and transmission industry. This material possesses excellent oxidation resistance, maintaining structural integrity for extended periods even under complex outdoor climates. There are several different types of custom fasteners that are commonly used in high voltage electrical equipment, each tailored to meet specific requirements and challenges. But if current flows through bolts,stainless steel bolts will heat more due to higher resistivity.
