Teyi Electric's TY series FRP electric meter boxes use SMC composite material compression molding technology, integrating high-strength glass fiber and unsaturated polyester resin, and have excellent insulation performance (withstands voltage above 10kV), impact strength (≥150MPa) and V-0 flame retardant properties. Its patented anti-aging formula enables the product to maintain stable operation for 30 years in harsh outdoor environments, and its indoor service life can reach 40 years, far exceeding traditional metal/plastic meter boxes. The innovative modular design supports free combination installation of 1-12 households, and the hidden wiring trough and IP55 protection level ensure safe and efficient electricity metering in residential areas, commercial power distribution and other scenarios, especially suitable for outdoor substation projects that require long-term weather resistance.
Operating temperature range is -25°C to +50°C, with a 24-hour average temperature limit of ≤+35°C.
Clean air without corrosive pollutants.
Relative humidity ≤80% at 40°C. Low temperature environments allow higher relative humidity (condensation should be avoided).
Built-in moisture-proof design to adapt to humidity fluctuations, meeting IP55 protection level (suitable for outdoor installation).
Rated current of the main busbar covers 10A to 250A, adapting to various power usage scenarios.
Rated short-time withstand current of the main busbar is up to 30kA, ensuring system integrity during power grid failures.
Insulation resistance ≥ 20MΩ (far exceeding conventional standards) and rated insulation voltage of 800V, building a double electrical barrier.
IP44 protection level design, effectively resisting dust intrusion and all-round splashing water.
Supports 50Hz/60Hz dual-frequency power grid system, meeting international standard application requirements.
30kA short-circuit withstand capability is equivalent to being able to withstand a peak current shock of approximately 63kA. The 800V insulation voltage provides a 15% safety margin for the 690V rated working voltage. The first "4" in the IP44 protection level indicates protection against solid foreign objects ≥1mm, and the second "4" represents splash water resistance.

The boxes are made using SMC composite material compression molding technology, which integrates high-strength glass fiber and unsaturated polyester resin. This provides excellent insulation performance (withstanding voltage above 10kV), high impact strength (≥150MPa), V-0 flame resistance, and a service life of up to 30 years outdoors and 40 years indoors.
They operate reliably within a temperature range of -25°C to +50°C (with a 24-hour average ≤+35°C). They can handle a relative humidity of ≤80% at 40°C, and feature a built-in moisture-proof design to adapt to fluctuating humidity levels.
The main busbar supports a rated current from 10A to 250A and has a rated short-time withstand current of up to 30kA. It also features a rated insulation voltage of 800V and an insulation resistance of ≥20MΩ.
The boxes meet IP55 protection standards overall, making them suitable for outdoor installation with built-in moisture protection. The specific IP44 design ensures protection against solid foreign objects ≥1mm and resistance to multi-directional water splashes.
The TY-SXD1-1C model represents a third-generation single-phase single-meter non-metallic SMC metering box. It comes configured with one miniature circuit breaker (Model CDBK C type 2P 6A) as the incoming switch.
The modular architecture supports free combination installations for 1 to 12 households, featuring hidden wiring troughs that optimize both residential and commercial power distribution layouts.
