China China TY-SXD1-FX Single-Phase One-Position Distribution Box from Leading Suppliers and Factory Manufacturer, Factories
Product Description
Product Overview
The TY series distribution box developed by Teyi Electric Co., Ltd. is manufactured using internationally leading SMC glass fiber reinforced composite materials through precision molding technology. Combining electromechanical performance with aesthetic structural design, it delivers standard-setting advantages:
Engineered with high mechanical strength, superior insulation, and fire-retardant properties. Outstanding corrosion and aging resistance delivers an indoor service life of up to 40 years and an outdoor service life exceeding 30 years.
Features a streamlined, smooth aesthetic profile. The versatile modular architecture accommodates flexible combination arrays suitable for single-household, multi-household, and cross-household requirements.
Integrated concealed wiring paths streamline field installation. The advanced rainproof and waterproof structure ensures high reliability in harsh outdoor environments, providing complete protection for energy measurement components.
Usage Environment
The TY series features both single-phase and three-phase enclosures, designed specifically for AC 50Hz/60Hz distribution frameworks, working voltages between 220V and 690V, and current ranges of 10A–250A. It manages energy measurement, power dispatching, and control safety.
Operating thermal range: -25℃ to +50℃ (average temperature within any 24-hour cycle ≤+35℃).
Clean air deployment; maximum relative humidity threshold of 80% at +40℃, allowing higher relative humidity at reduced operational temperatures.
Installation and Usage Specifications
- Pre-installation checks: Inspect every unit component fully to guarantee the absence of mechanical fractures or manufacturing defects.
- Vertical mounting: Ensure vertical alignment with a tilt angle ≤5° to minimize mechanical stress and avoid environments with excessive dynamic vibrations.
- Ambient location: Select cool, well-ventilated dry zones sheltered from constant direct UV rays and industrial chemical vapors.
- Prevent hard impacts and protect exterior surfaces against scratches caused by sharp instruments.
- Maintain clear, clean internal cable access; conduct periodic dust removal to ensure uninterrupted thermal dissipation.
Remove the two fixed screws from the bottom cover assembly.
Carefully open the enclosure housing per operational instructions.
Drill surface holes matching base positioning points and insert expansion tubes.
Mount the structural base plate securely, then reassemble the upper cover unit.
Core Electrical Parameters
- Rated operating current: 10A to 250A
- Rated short-time withstand current: 30kA/1s (Peak withstand current: 75kA/0.1s, coefficient 2.5)
- Rated insulation voltage: 800V
- Standard insulation resistance: ≥20MΩ (under standard testing conditions)
- Compatible power network frequency: 50Hz or 60Hz AC
- Ingress protection rating: IP44 (certified resistance against particles ≥1.0mm and multi-directional water spray)
Key Technical Description
- Short-Time Withstand Capability: The certified 30kA/1s threshold exceeds baseline load requirements in commercial power arrays, featuring a 2.5x peak current tolerance margin.
- Insulation Matching: The standard 800V insulation voltage comfortably accommodates low-voltage grids up to 690V, ensuring long-term operational safety.
- Protection Features: The IP44 physical shell reliably resists ingress in standard non-extreme outdoor operational environments while preserving active air convection.

The TY series distribution boxes are manufactured using precision-molded SMC (Sheet Molding Compound) glass fiber reinforced composite materials, providing high electromechanical insulation and weatherproofing.
Due to the corrosion and environmental aging resistance of composite SMC, the boxes achieve an operational life of over 40 years in indoor installations and over 30 years in standard outdoor environments.
The series supports AC 50Hz/60Hz grids with rated working voltages between 220V and 690V, continuous currents of 10A to 250A, an 800V rated insulation voltage, and an IP44 external ingress protection rating.
Boxes must be mounted vertically with a tilt angle not exceeding 5°. Operating ambient temperatures should remain within -25℃ to +50℃ (24-hour average ≤+35℃) under standard clean air conditions.
Avoid all contact with strong alkalis, oxidizing acids, ketones, amines, aromatic solvents, and chlorinated hydrocarbons, as these compounds will cause degradation or chemical damage to the composite material.
Installation involves removing the bottom two cover screws, accessing the interior casing, drilling mounting holes in alignment with the internal markings, installing expansion tubes, securing the base, and fastening the upper cover.
