The 12kV Center Distance 275mm Embedded Pole is manufactured in strict accordance with the latest industry standards, specifically T/CEC 952-2024, the technical specification for solid-sealed poles used in AC metal-enclosed switchgear and controlgear for rated voltages from 12kV to 40.5kV . This compliance ensures that the component meets rigorous requirements for design, construction, testing, and marking, providing engineers and procurement specialists with confidence in its quality and reliability for medium-voltage switchgear applications.
Adherence to this group standard, which was implemented on March 1, 2025, guarantees that the embedded pole has undergone a comprehensive suite of type tests . These include verification of its power frequency withstand voltage (48kV) and lightning impulse withstand voltage (85kV) , confirming its dielectric strength under both normal and transient overvoltage conditions . The standard also mandates specific mechanical endurance, validated by the product's 10,000-operations mechanical life..jpg)
Beyond the core standard, the embedded pole is designed to meet the requirements of its intended application, such as within IEC 62271-200 compliant switchgear . This dual compliance ensures seamless integration into both domestic and international power distribution projects. The component's rated short-time withstand current of up to 31.5kA for 4 seconds is a critical parameter verified during standardized testing, assuring its ability to withstand fault currents for proper protection coordination .
The manufacturing process itself is governed by strict quality control measures aligned with these standards. The use of automatic pressure gelation (APG) technology for the epoxy resin ensures void-free insulation, which is fundamental to achieving the specified partial discharge level of ≤5pC . This low partial discharge level is a key indicator of long-term insulation reliability and is a direct result of adhering to best practices outlined in industry specifications.
Therefore, the 12kV center distance 275mm embedded pole represents a component that is not only technically advanced but also fully certified against the latest industry benchmarks, minimizing risk for switchgear manufacturers. Putai also supports customization and the supply of related medium-voltage accessories to meet system integration needs.
