Yueqing, Wenzhou Rooted in China's Electrical Capital
Our base sits inside one of the world's densest clusters of electrical component suppliers, shortening lead times for breakers, terminals and metering accessories.
Zhejiang Teyi Electric Co., Ltd. designs, develops and manufactures power metering and distribution enclosures for utilities, EPC contractors and electrical distributors who cannot afford field failures.
Based in Yueqing, Wenzhou, our engineers work every day with SMC fiberglass compression molding and stainless steel fabrication. Our portfolio covers single- and three-phase energy metering boxes, cable branch boxes, photovoltaic grid-connection boxes, JP cabinets, high- and low-voltage switchgear, pole-mounted circuit breakers and power manhole covers.
Guided by our principle of integrity, quality, innovation and win-win cooperation, we help buyers specify the right enclosure, validate it with samples and receive consistent batches on schedule.
Continuous investment in modern production equipment, process engineering and technical talent gives us a complete, in-house technology chain from product R&D to final inspection.

A quick engineering reference our team uses when helping procurement managers choose enclosure materials for tenders.
| Criterion | SMC Fiberglass (GRP) | Stainless / Painted Steel | Ordinary Plastic |
|---|---|---|---|
| Electrical insulation | Inherently insulating; no enclosure earthing path to energize | Conductive; relies on reliable earthing | Insulating |
| Corrosion & weathering | Does not rust; stable in humid and outdoor environments | Stainless resists well; painted steel needs coating upkeep | Can embrittle and fade under long UV exposure |
| Mechanical strength | High strength from glass-fiber reinforcement | Very high, heavier | Lower impact resistance |
| Typical service life | 40+ years indoor, 30+ years outdoor (Teyi TY-SXD2 design data) | Depends on grade and coating | Generally shorter outdoors |
| Best fit | Utility metering, residential, coastal and PV sites | Specs requiring metal, high tamper resistance | Low-cost indoor use |

Straight answers to the questions utilities, contractors and importers ask us most before placing an order.
Our metering and distribution boxes are compression-molded from SMC (sheet molding compound) unsaturated polyester glass-fiber reinforced plastic, which combines high mechanical strength with inherent electrical insulation. For projects that specify metal enclosures, we also manufacture stainless steel electricity meter cabinets.
For our TY-SXD2 single-phase multi-meter series, the designed service life exceeds 40 years for indoor installation and 30 years for outdoor installation, significantly longer than conventional metal or plastic meter boxes.
Standard models operate at ambient temperatures from -25°C to +50°C, with a 24-hour average not exceeding +35°C, and relative humidity up to 80% at 40°C in clean air. Tell us about coastal, high-altitude or high-UV sites so we can recommend the right configuration.
Yes. Through our OEM and ODM programs we adapt meter positions, dimensions, viewing windows, locking, cable entries, internal components, color and branding. Share your drawings or tender specification and our engineers will propose a compliant design under full confidentiality.
Yes. Our ODM service includes fast sample turnaround so you can evaluate fit, finish and performance before confirming a production order.
Our factory is in Yueqing Economic Development Zone, Wenzhou, Zhejiang Province, widely known as the Electrical Capital of China, giving us direct access to a mature supply chain for electrical components. We ship to customers worldwide.
