Explore our core product lineup: precision compression-molded SMC composite boxes, high-capacity collector panels, and heavy-duty floor-standing branch units tailored for overseas power utilities.
As modern distribution systems transition toward Smart Grids, Advanced Metering Infrastructure (AMI), and microgeneration systems, outdoor meter enclosures are no longer passive physical housings. They have evolved into critical frontline security perimeters for non-technical loss (NTL) prevention, wireless communication reliability, and grid resilience.
Global utilities lose over $96 billion annually to electricity theft. Next-generation outdoor meter boxes feature concealed internal hinges, proprietary mechanical locking, multi-point electronic micro-switches, and ultrasonic weld seals to defeat magnetic and bypass manipulation.
Traditional metallic enclosures act as Faraday cages, blocking wireless telemetry such as NB-IoT, LoRaWAN, Cellular 4G/5G, and Zigbee. Sheet Molding Compound (SMC) glass-fiber reinforced plastic guarantees high RF transparency without the need for external vulnerable antennas.
With urbanization expanding along coastal and tropical zones, standard painted mild steel boxes suffer severe galvanic corrosion within 3 to 5 years. Compression-molded GRP/SMC materials provide intrinsic zero-rust durability, withstand salt spray tests exceeding 1,000 hours, and resist severe UV degradation.
From centralized state utility tenders to private industrial microgrids, our manufacturing matrix meets rigorous localized criteria across Europe, Southeast Asia, South America, and Africa.
The TY-SXD2 series addresses multi-tenant metering in urban residential projects. Available in 2, 4, 6, 8, and 12-position configurations with segmented utility isolation barriers, individual breaker switches, and centralized transparent meter-reading panels.
Handling commercial loads demands robust busbar capacities. The TY-SXS3 Transformer-type 3-phase boxes integrate precision current transformer (CT) compartments, internal wire segregation, and safety interlocks for currents spanning 100A to 630A.
Decentralized rooftop PV arrays necessitate bi-directional revenue metering, AC surge protection devices (SPDs), and rapid disconnection switchgear. Our specialized PV boxes maintain UV stability under extreme thermal solar exposure.
Headquartered in Yueqing, Zhejiang—China's electrical engineering powerhouse—Zhejiang Teyi Electric adheres strictly to international mechanical and dielectric testing regimes.
Comprehensive standard testing for empty low-voltage switchgear enclosures, validating ingress protection (IP65) and thermal stability up to 960°C glow-wire flammability index.
Closed-loop, fully audited manufacturing protocols covering every stage: resin compounding, compression molding pressures, dimensional tolerance verification, and final packing.
SMC enclosures provide class-leading insulation resistance with breakdown voltages exceeding 10 kV/mm, safeguarding end users and utility personnel against stray-voltage accidents.
Turnkey mold creation, CAD/SolidWorks engineering verification, customized DIN-rail configurations, client logo debossing, and dedicated wire gland punch arrangements.

Universal multi-tier mounting systems that allow rapid on-site conversion between single-phase smart meters, split prepayment meters, and miniature breakers.
Advanced breathable Gore-membrane breathers integrated directly into cabinet roofs to eliminate internal condensation while maintaining IP65 watertight seals.
Review the continuation of our production catalog: single-phase modular boxes, heavy-duty three-phase transformer units, and junction boxes engineered to utility standards.
Comprehensive engineering insights addressing design parameters, mechanical strength, flammability standards, and custom tool manufacturing for international projects.
SMC (Sheet Molding Compound) unsaturated polyester glass-fiber reinforced plastic provides complete electrical insulation (eliminating the hazard of enclosure energization and reducing grounding overhead), zero galvanic corrosion in humid or coastal environments, and excellent RF transparency for wireless smart meters (AMI). Furthermore, SMC delivers a 40+ year indoor and 30+ year outdoor service life without requiring recurring anti-corrosion repainting.
Our raw material compounds include high-grade organic UV stabilizers and antioxidants mixed uniformly into the thermosetting matrix. Unlike standard ABS or PC thermoplastics that become brittle, chalk, and lose tensile strength after 3 to 5 years of intense outdoor exposure, our SMC boxes retain over 85% of their initial flexural strength and IK10 impact resistance after accelerated xenon-arc UV exposure tests (ISO 4892-2).
Yes. Zhejiang Teyi Electric operates an in-house precision mold engineering workshop in Yueqing. We offer full OEM and ODM capabilities, enabling modification of meter mounting spacing, DIN-rail setups, transparent viewing window placements, cable gland knockouts, and permanent company logo embossing or debossing directly into the tooling surface.
Our SMC formulations meet the UL94-V0 flammability classification, which guarantees self-extinguishing behavior within 10 seconds without flaming drips. Under IEC 60695-2-11 testing, our enclosures easily pass the 960°C glow-wire flammability index (GWFI), preventing internal arc flash or electrical fires from breaching the enclosure.
Standard catalog samples are typically dispatched within 3 to 5 business days. For customized enclosure prototypes requiring custom mold modification, sample lead time ranges from 15 to 25 days. Mass production for standard 20ft or 40ft high-cube containers generally completes within 20 to 30 calendar days, backed by our streamlined multi-press compression facilities in Wenzhou.
