1. Product overview

The low-voltage cable tapping box can be made of SMC composite material or stainless steel material box, which has good impact resistance, bending strength, aging resistance, high friction resistance, corrosion resistance, appearance and durability, convenient installation, high insulation strength, arc resistance, high flame retardant and other advantages. It can meet the needs of various harsh environments and places in outdoor engineering projects. It is suitable for power transmission and distribution in public places such as urban and rural power grid renovation, municipal projects, residential areas and high-rise buildings, and is used for the control and protection of dry wiring and branch lines of cables. The color of the box is generally * green and gray, and can also be selected according to user requirements.
