12kV high voltage insulation components are critical parts in 12kV electrical equipment, serving to isolate live conductors, withstand electrical stress, and support mechanical structures. They are widely used in switchgear, transformers, cable lines, and other equipment. Below is a detailed introduction covering materials, types, applications, technical requirements, and maintenance:
Primary Materials-Epoxy Resin
12kV insulation components must meet electrical strength requirements of power frequency withstand voltage ≥42kV (1 minute) and impulse withstand voltage ≥75kV, along with excellent mechanical strength and environmental adaptability.
Epoxy Resin Characteristics:High insulation strength (breakdown field strength ≥30kV/mm), exceptional mechanical strength (flexural strength ≥120MPa). Complex shapes can be formed via vacuum casting processes, making it ideal for cast insulation components.
Applications:Insulators, contact boxes, insulation barriers, bushings, etc.
Characteristics:Strong hydrophobicity (anti-condensation), temperature resistance (-60°C to 200°C), aging resistance, and elasticity. Suitable for outdoor or humid environments.
12kV high-voltage insulation components are the most widely used insulation equipment in the distribution network, and their performance directly affects the reliability of power supply. In practical applications, it is necessary to select appropriate materials and structures according to the equipment type (such as switchgear, cables) and environmental conditions (indoor/outdoor, pollution level), and ensure insulation safety through strict manufacturing processes and regular maintenance. With the intelligent upgrade of distribution networks, insulation components are developing towards high reliability, intelligent monitoring and green environmental protection.
