SMC cabinets
Overview
As an ideal substitute for the traditional metallic cabinets, the SMC cabinet is characterized by electrical & thermal insulation, flame retardation & low-smoke, aging resistance, corrosion prevention, heat & cold endurance, simple structure, easy assembly, esthetic appearance, light weight and flexible application. SMC HV/LV distribution cabinets and communication & control cabinets can be widely applied in transformer (distribution) stations, industrial and mining establishments, street/highway sides, residential quarters, commercial buildings and other public spaces.
