Wholesale 200 Amp Underground Meter Box Manufacturer & Factories

Underground meter boxes are engineered specifically for service entrance conductors emerging from below grade. They feature significantly deeper enclosures, expanded lower wire-bending troughs, and reinforced raceways to handle larger-gauge direct-burial or conduit-encased cables (such as 4/0 or 250 kcmil AL). Additionally, they often integrate dedicated underground pull sections separated from the metering compartment to permit utility line crews to draw conductors without disrupting the customer disconnect.

SMC is a high-strength composite made of chopped glass fibers impregnated with unsaturated polyester resin under extreme pressure and heat. It is an inherent electrical insulator, eliminating any danger of the enclosure becoming live during an internal flashover or fault. It will never corrode or rust when exposed to soil chemicals, direct UV radiation, moisture, or chemical sprays, offering a certified outdoor operational lifespan of more than 30 to 40 years with zero maintenance.

Yes. Zhejiang Teyi Electric operates full in-house tooling, CNC milling, and custom sheet metal and mold compression facilities. We regularly produce tailored configurations matching specific North American utility service requirements (such as ringless design with lever bypass, horn bypass), British Standard DIN rail arrangements, or IEC-compliant CT-operated multi-metering stations. Our engineering team provides detailed 3D CAD modeling and prototype samples prior to mass tooling.

Our standard production enclosures operate continuously within an ambient temperature spectrum of -25°C to +50°C (with peak resistance extending from -40°C to +120°C without mechanical failure). Because SMC has an exceptionally low coefficient of thermal expansion and poor thermal conductivity compared to steel, internal condensation buildup is minimized, preventing short circuits and corrosion on sensitive electronic smart meter components.

Every production batch undergoes strict quality checkpoints: dimensional accuracy verification, IP degree water-jet ingress testing (up to IP65/IP66), IK mechanical impact testing (up to IK10), high-voltage dielectric withstand tests, flame retardancy validation (UL94-V0 compliance), and mechanical torque tests on all busbar terminal lugs. Full third-party inspection reports can be coordinated upon request.

For standardized catalogue models, standard MOQs begin at 50 to 100 units, with typical production lead times ranging from 15 to 25 working days. For custom OEM or ODM orders requiring new press molds, mold production requires approximately 30 days, followed by rapid sample validation within 7 days. We support mixed-container shipments containing meter boxes, cable branch cabinets, and switchgear components directly from our Yueqing manufacturing hub.
