Frequently Asked Questions (FAQ)
What material is used for the TY series electric energy metering box?
The box is made of SMC composite material (glass fiber reinforced unsaturated polyester resin) molded in one piece, which provides high mechanical strength, dimensional stability, and impact resistance.
What is the expected service life of these SMC metering boxes?
These cabinets feature an ultra-long service life, exceeding 40 years for indoor installations and over 30 years for outdoor applications, which significantly outperforms traditional metal or plastic boxes.
Do these metering boxes require grounding for safety?
No, the SMC composite material provides natural insulation with an insulation resistance of ≥ 20MΩ, eliminating the risk of leakage without requiring grounding.
What are the environmental limits for installing the TY series boxes?
They operate reliably in temperatures ranging from -25℃ to +50℃ (average 24h temperature ≤ +35℃) and relative humidity up to 80% at 40℃ in clean air environments. The material itself can withstand -50℃ to 160℃.
What is the difference between TY-DXZB-1 and TY-SXZB-1 models?
The TY-DXZB-1 is designed for single-phase applications with a 100A incoming disconnector, whereas the TY-SXZB-1 is designed for three-phase applications with a 200A incoming disconnector.
