Product profile:
Epoxy resin insulating sleeve is a high-performance insulating component designed for medium and high-voltage electrical equipment. It is made of high-strength epoxy resin material through precision molding process and integrates a corrugated insulating barrel body and a stable base. This product has electrical insulation, mechanical support and electric field control functions. It is suitable for switchboards, cable terminals, transformers and other scenarios. It can effectively isolate high-voltage conductors and grounded parts, prevent arcing and short circuit risks, and at the same time resist mechanical vibration and electromagnetic force impact, ensure long-term stable operation of the equipment.
As the core insulation protection component of medium and high voltage systems, this product mainly achieves the following functions:
·High-voltage insulation isolation: Through high dielectric strength epoxy resin material and optimized structural design, the electrical path between the conductor and the housing is blocked to avoid leakage or breakdown.
·Mechanical support and fixation: The base is designed to adapt to bolt installation to stably bear the weight of the conductor and the electromagnetic force generated by short-circuit current to prevent displacement or deformation.
·Electric field homogenization: The corrugated cylinder structure disperses the electric field concentration area, reduces partial discharge (PD) levels and extends equipment life.
·Material optimization: Select high-purity epoxy resin, add anti-aging and arc-resistant components to ensure stable performance across a wide temperature range of-40℃ to +150℃, and the flame retardant rating reaches UL94V-0.
·Structural innovation:
·Corrugated cylinder body: Increase creepage distance and adapt to high humidity, dust or salt fog environments (such as coastal/industrial areas).
·Integrated base: Square design improves installation stability, supports embedded or flanged connections, and is compatible with multiple equipment interfaces.
·Metal inserts: The top conductor inserts are made of copper and silver plating to reduce contact resistance; the base bolts are rust-proof and have strong corrosion resistance.
·High reliability: partial discharge value ≤ 5pC (1.1 times rated voltage), far below industry standards, ensuring long-term trouble-free operation of the insulation system.
·Strong environmental adaptability: Creepage distances can be customized to meet different pollution levels specified in IEC 60815 (such as Class III/IV), suitable for extreme working conditions.
·Combination of standardization and customization: Conventional products cover voltage levels from 12kV to 36kV, and also support flexible customization of size, interface and installation methods to adapt to personalized engineering needs.
·Power distribution: 10kV-40.5kV high-voltage switchgear (such as KYN61, XGN15 series), ring network cabinet bus support.
·Energy equipment: insulation protection of transformer outlet bushings and cable terminals.
·Industrial scenarios: Medium voltage distribution systems in data centers, rail transit, and new energy power stations (such as wind power/photovoltaic).
The product is certified by international/domestic standards such as IEC 60273 and GB/T 8287, and provides complete type test reports (including withstand voltage, temperature rise, and mechanical strength tests) to ensure compliance with power grid security access requirements.
