China Suppliers Factory TY-SXS2-DXJ Low Voltage Three-Phase Two-Position Electric Energy Metering Box
Product Overview
The TY series FRP electric energy metering boxes developed by Teyi Electric Co., Ltd. are made of SMC unsaturated polyester resin glass fiber reinforced plastics through compression molding. They have the characteristics of reliable insulation, high strength, good flame retardancy, corrosion resistance, aging resistance, novel shape, smooth and beautiful surface, etc. The service life is more than 40 years indoors and more than 30 years outdoors, which is incomparable to other metal plastic electric meter boxes. This product is widely used in residential construction and civil power transformation. It can be combined with multiple households at will, and can also be installed in a single household or across households. It is easy to construct and has concealed wiring. This product adopts a strict rainproof design and is suitable for outdoor installation to ensure the safe operation of the electric meter.
Product Installation and Use
After unpacking, you need to systematically check the integrity of the box, fasteners and internal structural parts to confirm that there is no transportation damage (it is recommended to keep unpacking video records).
- Verticality deviation of the mounting surface ≤54° (needs to be calibrated using a level gauge)
- The site selection should avoid vibration sources (such as within 3m of large equipment) and chemical corrosion areas (200m downwind of chemical enterprises)
- Do not expose to strong acid (pH < 2), strong alkali (pH > 12) and organic solvent environment
- ① Loosen the two M6 stainless steel fixing screws at the bottom (torque ≤ 8N·m)
- ② Separate the top cover and the base according to the "Product Disassembly and Assembly Guide"
- Position according to the Φ8mm mounting holes on the back of the box (spacing standard: horizontal 400±2mm, vertical 300±2mm)
- Use M8 expansion bolts (tensile strength ≥ 50kN) to fix, the recommended embedding depth is ≥ 60mm
- The cable introduction must maintain a bending radius ≥ 5D (D is the outer diameter of the cable)
- The grounding terminal should be connected with 16mm² yellow-green two-color copper core wire
- UV Protection: A sunshade should be installed in areas with continuous sunlight (ASA material is recommended)
- Mechanical Protection: Anti-collision warning signs are set within 1.2m around
- Chemical Protection: Only use neutral detergent (pH 6-8 range) for cleaning

Frequently Asked Questions (FAQ)
They are made of SMC (Sheet Molding Compound) unsaturated polyester resin glass fiber reinforced plastics through compression molding, offering reliable insulation, high strength, flame retardancy, and corrosion resistance.
The expected service life is more than 40 years for indoor installations and more than 30 years for outdoor environments.
The TY series features a current range of 10-250A, short circuit tolerance of 30kA/1s, insulation characteristics ≥20MΩ (800V), grid frequency of 50/60Hz, and an IP44 protection level against dust and water splashes.
Site selection must avoid vibration sources within 3m of large equipment, areas within 200m downwind of chemical enterprises, and environments exposed to strong acid (pH < 2), strong alkali (pH > 12), or organic solvents.
The cable introduction must maintain a bending radius ≥ 5D (where D is the cable outer diameter), and the grounding terminal must be connected using a 16mm² yellow-green two-color copper core wire.
For UV protection in continuous sunlight, install a sunshade (ASA material recommended). Set anti-collision warning signs within 1.2m around, and use only neutral detergents (pH 6-8) for cleaning.
