The contact box is formed by epoxy resin with APG technology, it is used for insulation, isolation & connection transition in various kinds of handcart switchgear.
Key Features:
High Voltage Rating: Rated for up to 10kV, ideal for medium-voltage electrical systems.
Epoxy Resin Construction: Durable and strong, providing excellent dielectric properties and electrical insulation.
Corrosion Resistant: Designed to resist moisture, dust, and chemical exposure, making it highly suitable for outdoor and harsh indoor environments.
Compact & Robust Design: Offers high mechanical strength, capable of withstanding impacts and vibrations.
Easy Installation: Simple to integrate with electrical equipment, reducing installation time and costs.
Long Service Life: Low maintenance requirements and resistance to aging, ensuring long-term reliability.
Working conditions
1.Altitude: ≤1000m
2.Ambient temperature at -30℃ to +40℃, the daily average temperature should not more than 30℃
3.The daily average of relative humidity is less than 95%, the average monthly is less than 90%.
4.Working environment should be without steam, gas, chemical corrosive deposition, salt fog, dust, dirt and other dangerous explosive media, which will severely impact on insulation and conductivity of products.
5.Working environment should not be regular vibration or serious bumps
