Product Overview
The transparent meter box is mainly made of flame-retardant polycarbonate (PC) injection molding, and the bottom of the box is made of polycarbonate and acrylonitrile butadiene styrene copolymer engineering plastic (PC+ABS) injection molding. The box has insulation, high temperature resistance, aging resistance, impact resistance, anti-corrosion, moisture-proof, waterproof, safe and reliable properties. The electricity metering device is fully enclosed and managed, with functions such as closed metering circuit, prevention of electricity theft, and easy meter reading.
