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. 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, meeting both functional requirements and aesthetic value. The modular structure design supports flexible combination installation of single, multiple, 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.
- Temperature range: -25℃ ~ +50℃ (average temperature within 24 hours ≤ +35℃)
- Humidity requirements: Clean air; upper limit of relative humidity is 80% at 40℃
- Low temp compatibility: Compatible with higher humidity levels under low temperature conditions
- Frequency: AC 50Hz or 60Hz
- Working Voltage: 220V to 690V
- Current Range: 10A to 250A
Installation and Usage Specifications
Pre-installation checks: Before installation, the integrity of each component of the meter box must be fully checked to ensure that there are no defects or abnormalities.
Installation positioning requirements:
- 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.
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.
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.
Cabinet installation process:
-
1
Remove the two screws fixing the upper cover at the bottom of the box.
-
2
Open the box according to the instructions.
-
3
Drill holes according to the positioning holes and install the expansion tube.
-
4
After fixing the base, assemble the upper cover.
