Product Introduction
The 3# internal cone insulator is a core insulated component for 10～35kV high-voltage electrical equipment. It is made of high-quality epoxy resin through APG vacuum precision molding, and is specially designed for the internal cone conductor docking of high-voltage switchgear, GIS, ring main unit and other equipment. Its core function is to realize insulation isolation and sealing protection between the conductor and the grounded shell, adapt to the standardized 3# internal cone installation cavity, and has excellent insulation, sealing and mechanical properties to ensure the safe and stable operation of high-voltage power transmission and distribution equipment.Product Overview
The 3# internal cone insulator is based on high-performance epoxy resin and specially designed for the internal cone conductor docking and insulation protection needs of 10～35kV high-voltage equipment. Its core highlight is the internal cone integrated epoxy structure, which balances high-voltage insulation reliability and installation convenience. It solves the insulation and sealing problems of conductor connection parts in high-voltage equipment, and provides an efficient insulation connection solution for high-voltage power transmission and distribution equipment.1. Structural Features
- Internal cone integrated structure: Adopting standard 3# internal cone angle and one-piece epoxy molding with embedded high-quality metal conductive parts, it can be directly docked with high-voltage conductors, ensuring insulation and conductivity reliability, and adapting to high-voltage electric field distribution.- Sealing protection design: Full epoxy sealing + special sealing groove can prevent SF6 gas leakage and the intrusion of external dust and moisture, avoiding insulation failures caused by sealing failure.- Installation adaptability: Embedded installation with small tolerance, it can be accurately docked with the high-voltage equipment cabinet body, adapted to three-phase common cylinder and single-phase single cylinder high-voltage equipment, and conforms to the 3# internal cone installation standard.2. Performance Advantages
- High insulation strength: CTI≥600V, dielectric strength≥28kV/mm, which can effectively resist the risk of high-voltage insulation breakdown at 10～35kV, meeting the high-voltage insulation technical requirements.- Mechanical and environmental adaptability: Compression and impact resistant, with bending strength exceeding 200MPa; operating in a wide temperature range (-40℃～+150℃), resistant to SF6 corrosion and ultraviolet rays, and adapted to complex working conditions such as high altitude and industrial pollution areas.3. Typical Application Scenarios
It is suitable for 10～35kV high-voltage switchgear, GIS/gas-insulated ring main unit, substation complete sets of equipment and high-voltage equipment in special environments, meeting the insulation connection needs of various high-voltage power transmission and distribution scenarios.4. Core Values
