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.

Product Description

Materials and Manufacturing Process

SMC Composite Materials

Molded by unsaturated polyester resin glass fiber reinforced plastic (SMC), offering high mechanical strength and permanent anti-deformation properties. Completely solves typical metal and plastic defects such as easy corrosion, aging, and poor insulation.

Surface Process Optimization

Smooth and elegant surface treatment designed to resist ultraviolet (UV) radiation and chemical media (weak acid, alkali) corrosion. Perfectly suited for industrial waste gas zones and coastal environments with high salt fog.

Core Performance Advantage

Electrical Safety

Insulation resistance ≥ 20MΩ with a flame retardant grade of UL94 V0, effectively isolating potential arc discharge risks.

Environmental Durability

Outdoor service lifespan > 30 years and indoor lifespan > 40 years, lasting more than twice as long as traditional metal cabinets.

Protection Capability

Features an advanced rainproof structure certified with an IP44 protection level, blocking dust accumulation and foreign object intrusion.

Anti-Electricity Theft

Equipped with reliable lead locks and fully concealed internal wiring configurations to effectively prevent any unauthorized operation.

Installation and Scene Adaptability

Flexible Deployment Mode

Supports wall mounting, pole fixing, or embedded wall installation. Fully compatible with single-family or multi-family aggregated installations without requiring additional modification for cross-family wiring.

Widely Applicable Scenarios

Civilian Field: Residential developments and legacy power transformation projects; highly suited for prepaid meters and leakage protection systems.
Outdoor Scenarios: Engineered rainproof design secures long-term metering reliability under operating temperatures ranging from -25℃ to +50℃.

Convenient Operation and Maintenance

Frequently Asked Questions (FAQ)

What are the main advantages of SMC composite material over traditional metal cabinets?

SMC (Sheet Molding Compound) material delivers superior electrical insulation, high mechanical stability, and high resistance to chemical erosion and UV exposure. It prevents corrosion and oxidation common with metal cabinets, significantly extending service life to over 30 years outdoors without maintenance.

What is the ingress protection (IP) rating of these metering boxes?

The boxes are engineered with an IP44 protection rating. This ensures internal electrical parts are safeguarded against water splashing from all directions and prevents solid foreign particles larger than 1mm from entering.

How does the design prevent electricity theft?

Safety is ensured through an anti-electricity theft architecture featuring integrated lead seal locking positions, hidden mounting screws, and completely concealed wiring designs that eliminate unauthorized external access.

Can these enclosures withstand harsh environmental temperatures?

Yes. The enclosures are designed to maintain full physical structural stability and electrical safety performance across temperatures from -25℃ to +50℃, making them suitable for sub-zero climates as well as intensely hot regions.

What mounting and installation options are supported?

The structural layout flexibly supports outdoor pole fixing, direct wall surface mounting, or flush wall embedding without requiring complex modifications during cross-family power cable configurations.
