Wholesale China Suppliers Factory TY-DXZB-1 Single-Phase & TY-SXZB-1 Three-Phase Intermediate Protection Boxes Supplier, Factory
Product Description
Overview
Material and Process Characteristics
1. Basic Materials
The SMC composite material (glass fiber reinforced unsaturated polyester resin) is molded in one piece, giving the box high mechanical strength and dimensional stability.
2. Safety Performance
Insulation resistance ≥ 20MΩ, natural insulation without grounding, eliminating the risk of leakage; The flame retardant grade reaches FV0, and no toxic gas is released at high temperature.
3. Environmental Adaptability
Acid and alkali corrosion resistance, UV aging resistance, applicable temperature range -50℃~160℃; The surface is smooth and beautiful, impact-resistant and scratch-resistant.
Lifespan and Application Design
1. Ultra-Long Life
Over 40 years of indoor use and over 30 years of outdoor use, significantly exceeding traditional metal/plastic cabinets.
2. Flexible Installation
It supports free combination of single-household and multi-household as well as cross-household installation, which is suitable for residential construction and civil power transformation scenarios; the concealed wiring design simplifies the construction, and the IP54 protection level ensures the reliability of outdoor rain and dustproof.
