ANSI 1.2kV High Current Insulating Bushing(417-1227A )

This ANSI standard bushing is a high-voltage insulating component developed and manufactured in strict accordance with American ANSI electrical standards. It has a rated voltage of 1.2kV and covers full-gradient rated current specifications from 417A to 1227A, adapting to the general working conditions of North American power systems and American-style electrical equipment. Adopting a composite insulating structure, the product has excellent insulation voltage resistance, leakage prevention and aging resistance. It can operate stably in complex industrial environments such as high and low temperature, outdoor humidity and heat, dust and pollution.

Product description

                                                                                                     

 

Adopting a modular integrated structure design, the product has sturdy and durable core components with clear division of labor, and the overall structure is adapted to the installation system of American standard equipment. The specific components are as follows:
Conductive Core: Made of high-purity electrolytic copper, it has excellent conductivity and ultra-low resistance, with stable current bearing and no heating overload. It can withstand long-term rated large current of 417~1227A, and has good oxidation resistance and electric corrosion resistance to ensure safe and stable conductive paths.
Main Insulation Layer: Made of imported epoxy glass composite material and cured by high temperature and high pressure, it has high insulation strength and good compactness. It can stably withstand the rated working voltage of 1.2kV, effectively isolate live parts from equipment shells, and eliminate the risk of electric leakage and short circuit.
Sealing Protection Layer: Adopting weather-resistant silicone rubber sealing structure to wrap the bushing connection port, it has waterproof, moisture-proof, dust-proof and pollution-proof properties, preventing water vapor and dust from invading the insulation layer and protecting the core structure from environmental erosion.
Fixed Mounting Flange: American standard standardized flange structure with dimensions compliant with ANSI installation specifications and standard positioning holes. It is easy to install with tight fitting, no looseness or offset after fixing, and adapts to the general installation stations of American-style switch cabinets and transformers.
End Protective Head: The insulating protective head effectively prevents end arc discharge and creepage, buffers the loss of the bushing caused by equipment operation vibration, and prolongs the service life of the product.

Core Advantage

Wide Current Coverage & Multi-scenario Adaptability

The current specifications cover the full gradient range of 417A-1227A, meeting the needs of small, medium and high-power power distribution equipment. A single series of products can satisfy the current bearing requirements of different working conditions such as civil building power distribution, industrial and mining equipment, small and medium-sized transformers, and new energy power distribution equipment, with simple selection and wide adaptability.

Superior Insulation Performance & Stable Operation

The epoxy glass insulation material combined with integral molding process has excellent insulation compactness without pores or gaps, effectively eliminating partial discharge, creepage and insulation breakdown. It can withstand the rated 1.2kV voltage for a long time, with arc resistance and high voltage resistance, avoiding equipment short circuit and electric leakage faults, and ensuring the continuous and stable operation of the power system.

Excellent Weather Resistance & Long Service Life

The core material has excellent high and low temperature resistance, moisture and pollution resistance, and aging resistance. It can operate stably for a long time in harsh environments such as outdoor open air, humid mines, dusty workshops and severe temperature differences. It will not crack, pulverize or decay in insulation performance after long-term use, requiring no frequent maintenance and greatly reducing equipment operation and maintenance costs.

High-efficiency & Low-loss Conductivity

The high-purity copper core has high conductivity and extremely low current transmission loss. There is no obvious heating or voltage drop under high current working conditions, which effectively improves the operating efficiency of power distribution equipment, reduces power energy consumption, and complies with North American energy-saving power distribution standards.
