China TY-SXD1-1C Single-Phase Collector Box - Reliable Electrical Energy Management by Top Suppliers and Factory
Product Overview
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.
Usage Environment
-
Temperature Adaptability: Operating temperature range is -25°C to +50°C, with a 24-hour average temperature limit of ≤+35°C.
-
Environmental Cleanliness: Clean air without corrosive pollutants.
-
Humidity Control: Relative humidity ≤80% at 40°C. Low temperature environments allow higher relative humidity (condensation should be avoided).
-
Protection Performance: Built-in moisture-proof design to adapt to humidity fluctuations, meeting IP55 protection level (suitable for outdoor installation).
Core Electrical Performance
-
Wide Range Current Capacity: Rated current of the main busbar covers 10A to 250A, adapting to various power usage scenarios.
-
Extreme Short-Circuit Protection: Rated short-time withstand current of the main busbar is up to 30kA, ensuring system integrity during power grid failures.
-
Insulation Safety Guarantee: Insulation resistance ≥ 20MΩ (far exceeding conventional standards) and rated insulation voltage of 800V, building a double electrical barrier.
Environmental Adaptability
-
All-Weather Protection Architecture: IP44 protection level design, effectively resisting dust intrusion and all-round splashing water.
-
Global Frequency Compatibility: 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.

Frequently Asked Questions (FAQ)
What material is used in the TY series electric meter boxes, and what are its benefits?
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.
What are the temperature and humidity limits for operating these meter boxes?
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.
What are the core electrical ratings of the TY series meter boxes?
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.
What is the difference between the IP55 and IP44 ratings mentioned for these boxes?
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.
What configuration is included in the TY-SXD1-1C model?
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.
