Tight Tolerances for Gas-Insulated Switchgear
Our copper conductive rod for ring main unit is made specifically for gas-insulated switchgear. Ring main units and gas-insulated switchgear have very compact internal spaces. All components are sealed inside a housing filled with sulfur hexafluoride gas. The rod must connect switches and busbars in a very small space. Our team applies extra tight tolerance controls when processing this product. There is no adjustment room inside the housing. Even one millimeter off means it will not fit. We set tighter tolerance ranges specifically for this product.
Custom Specifications
Copper conductive rod for ring main unit follows your custom drawings for length and thread specifications. The material is T2 copper. Production follows GB/T5585.1-2026. Copper purity is above 99.90%. Total impurities stay within 0.10%. Conductivity is not less than 97.3% IACS. Resistivity at 20°C does not exceed 0.0177 Ω·mm²/m. Density is 8.9 g/cm³. Tensile strength ranges from 220 to 260 MPa. Yield strength is above 170 MPa. Hardness falls between 65 and 90 HV. Elongation is not less than 17%.
Stricter Tolerances for Switchgear
We apply tighter machining tolerances for this product. We check threads with go/no-go gauges on every piece. Third-party inspection is welcome. Our raw material inventory stays well-stocked. We deliver custom orders within one to two weeks after receiving drawings. The minimum order is 1000 kilograms. Every piece of copper conductive rod for ring main unit we produce fits within the tight tolerance range.
Gas-Insulated Switchgear Applications
This product is used in sulfur hexafluoride gas-insulated switchgear. Medium and high voltage gas-insulated distribution equipment also uses it. We have supplied switchgear manufacturers for many years. Now we are expanding our export business. Before production, we carefully check thread specifications and length. During production, we provide sample confirmation. After production, we use protective packaging. Choose our copper conductive rod for ring main unit for precision gas-insulated switchgear connections.
Guarantee and Order Terms
The material meets T2 copper standards for life. We do not offer free samples. Custom orders require 50% deposit. The remaining 50% is paid before shipping. We support EXW and FOB terms. USD, EUR, and CNY are accepted.
