– Product Model: 803591056
– Product Name: Middle Insulator
– Material specifications: High-purity insulating base material, high insulation strength, good temperature and pressure resistance, anti-breakdown and anti-aging, and stable protective performance.
The 803591056 middle insulator can solve problems such as insulation failure in the middle of the motor, phase-to-phase leakage, arcing, insulation aging and damage, insufficient electrical clearance, high-temperature cross-contamination, and short circuits. It is suitable for scenarios such as replacement of old parts, motor electrical maintenance, original factory assembly of new machines, insulation fault repair, and motor protection upgrade. The product is made of high-purity insulating substrate with high-strength curing process, and is made through precision cutting and shaping, insulation strengthening, temperature resistance reinforcement, and anti-aging treatment. The material is dense and uniform, with excellent insulation performance. It has the characteristics of high temperature resistance, high pressure resistance, breakdown resistance, aging resistance, heat insulation and anti-seepage. It is suitable for the harsh working conditions of engineering machinery with high frequency start-stop, high temperature operation, dust and oil, and large temperature difference, and provides long-term protection for the electrical insulation and isolation performance of the middle of the motor.

– Product Name: Middle Insulator
– Material specifications: High-purity insulating base material, high insulation strength, good temperature and pressure resistance, anti-breakdown and anti-aging, and stable protective performance.
– Processing technology: precision cutting and shaping, flattening and curing, insulation reinforcement, and temperature resistance treatment, meeting the quality inspection standards of original parts.
– Performance and operating condition adaptability: Excellent insulation and isolation effect, anti-arc and anti-aging, suitable for long-term high-temperature operation of motors.
– Structural features: Original factory standard specifications, precise and tight fit, easy disassembly and assembly, reducing electrical maintenance costs.
This product undergoes multiple specialized tests before leaving the factory, including insulation withstand voltage, high temperature insulation, arc breakdown resistance, dimensional compatibility, and aging durability, meeting the original equipment manufacturer (OEM) assembly standards for construction machinery. After installation, it precisely adapts to the insulation protection requirements of the motor’s central section, providing robust isolation and stable protection. It completely eliminates potential hazards such as leakage, arcing, cross-current, and insulation failure, effectively protecting the motor’s electrical components and the machine’s structure. This mitigates the risk of electrical fault downtime, reduces the frequency of insulation component replacement, and ensures the long-term safe, stable, and efficient operation of the construction machinery’s motor and electrical system.
