Wholesale TY-SXD1-FX single-phase one-position distribution box Manufacturer, Factory
Product Description
Product Overview
The TY series distribution box developed by Teyi Electric Co., Ltd. are made of internationally leading SMC glass fiber reinforced composite materials and refined through precision molding technology. This product combines excellent electromechanical performance with aesthetic design and has the following significant advantages:
It has super insulation, mechanical strength and flame retardant properties, outstanding corrosion resistance and aging resistance, and its indoor service life can reach 40 years and outdoor service life is more than 30 years, far exceeding traditional metal plastic meter boxes.
It adopts a streamlined appearance design with a smooth and bright surface, which not only meets functional requirements but also has aesthetic value. The modular structure design supports flexible combination installation of single households, multiple households and cross-households.
The concealed wiring design simplifies the construction process, and the strict waterproof and rainproof structure ensures the reliability of outdoor installation, providing all-round protection for power metering equipment.
Usage Environment
The TY series of electric meter boxes of Teyi Electric Co., Ltd. integrates two categories: single-phase and three-phase. They are designed for power supply systems with AC 50Hz or 60Hz, rated working voltage 220V to 690V, and current 10A-250A, realizing efficient integration of single-phase electric energy metering and power electric energy control management. This series of products has excellent environmental adaptability, with an applicable temperature range of -25℃～+50℃ (average temperature within 24 hours ≤+35℃); humidity requires clean air, and the upper limit of relative humidity is 80% at 40℃, and it is compatible with higher humidity levels under low temperature conditions.
Installation and Usage Specifications
Before installation, the integrity of each component of the meter box must be fully checked to ensure that there are no defects or abnormalities.
- Vertical installation: The tilt angle should be ≤5° to avoid vibration, impact and corrosive environment.
- Environmental selection: Prefer a cool and dry place, away from direct sunlight and chemical contact areas.
Chemical Protection Warnings: It is strictly forbidden to contact with strong alkali, oxidizing acid, amine, ketone, chlorinated hydrocarbon and aromatic solvent to prevent the material from dissolving or corroding.
Physical protection measures: Avoid sharp objects from colliding with or scratching the surface of the cabinet. The wiring area needs to be kept clean and dust must be removed regularly to ensure heat dissipation.
- Remove the two screws fixing the upper cover at the bottom of the box;
- Open the box according to the instructions;
- Drill holes according to the positioning holes and install the expansion tube;
- After fixing the base, assemble the upper cover.
Core Electrical Parameters
- Rated operating current range: 10A~250A
- Rated short-time withstand current: 30kA/1 second (corresponding to peak withstand current 75kA/0.1 second, coefficient 2.5)
- Rated insulation voltage: 800V
- Normal insulation resistance: ≥20MΩ (standard test conditions)
- Compatible frequency: 50Hz or 60Hz AC system
- Protection level: IP44 (protected against solid foreign objects with a diameter of ≥1mm and splashing water from all directions)
Key Technical Description
- Short-time withstand capability: The 30kA/1 second indicator meets the needs of most power distribution scenarios, and its peak withstand current is designed to be 2.5 times the international standard.
- Insulation matching: 800V insulation voltage covers power supply systems of 690V and below, leaving sufficient safety margin.
- Protection features: IP44 level is suitable for non-extreme pollution environments, and takes into account the balance between heat dissipation and protection.

Frequently Asked Questions (FAQ)
The TY series distribution boxes are manufactured using internationally advanced SMC (Sheet Molding Compound) glass fiber reinforced composite materials processed through precision molding.
Due to its excellent anti-aging and anti-corrosion properties, the indoor service life can reach up to 40 years, and the outdoor service life can exceed 30 years.
The box is designed for environments ranging from -25℃ to +50℃ (24h average ≤+35℃) with relative humidity up to 80% at 40℃. It should be installed vertically (tilt ≤5°) in cool, dry areas.
It offers an IP44 protection level, effectively preventing the ingress of solid foreign objects with a diameter of ≥1mm and shielding against water splashes from any direction.
Contact with strong alkalis, oxidizing acids, amines, ketones, chlorinated hydrocarbons, and aromatic solvents must be strictly avoided to prevent chemical erosion or dissolution of the SMC material.
