What materials are Teyi electricity meter boxes made of?

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.

What is the expected service life of an SMC fiberglass meter box?

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.

Which environmental conditions are the meter boxes designed for?

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.

Can Teyi customize meter boxes to our utility or tender specification?

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.

Do you provide samples before mass production?

Yes. Our ODM service includes fast sample turnaround so you can evaluate fit, finish and performance before confirming a production order.

Where is the Teyi Electric factory located?

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.

Frequently Asked Questions (FAQ)

What are the primary functions of the TY series electric energy metering box?

The TY series metering box delivers four key functions: precise energy metering for three-phase power systems, voltage signal conversion via transformers for safety, real-time monitoring of operational data (current, voltage, power), and essential circuit protection against overloads and short circuits.

What are the rated electrical parameters for the TY series metering box?

It operates on AC frequencies of 50Hz or 60Hz, with rated working voltages supported up to 220V, 380V, and 690V, and accommodates a rated operational current ranging from 10A to 250A.

What does the model code designation "SMC" stand for in TY-SX series?

In the model breakdown, "SX" specifies an SMC (Sheet Moulding Compound) non-metallic metering enclosure, which provides high insulation, durability, and corrosion resistance for metering systems.

What is the difference between model TY-SXS3-1A and TY-SXS3-2A?

TY-SXS3-1A is configured with one CDMK-250C/3300 250A incoming switch and one 250A outlet switch. In contrast, TY-SXS3-2A is equipped with a 250A total incoming line switch and two separate outlet switches (one 200A and one 125A), allowing multi-circuit distribution.

Where can the transformer-type metering box be applied?

It is engineered for diverse environments including industrial enterprises (production lines and workshops), commercial complexes, power utility distribution networks and substations, as well as institutional public facilities like schools and hospitals.

Does the TY series support both single-phase and three-phase measurement?

Yes, the product application scope covers both single-phase and three-phase meter box assemblies for comprehensive electrical measurement and power distribution management.
