Landscape-type Substation Product Introduction

1. Product Brief Introduction

The landscape-type substation is an integrated prefabricated complete set of power distribution equipment combining power distribution functions with environmental aesthetics. Taking the simulated landscape box as the carrier, it integrates transformers, high and low voltage switchgears, protection & measurement & control devices, metering & compensation and other core components. On the basis of meeting the conventional functions of power distribution, grid connection and protection, it achieves seamless integration with the surrounding residential, municipal, commercial and residential environments through customized modeling, color matching, material imitation and other designs of the landscape box body, replacing traditional box-type substations with high reliability, aesthetics and environmental compatibility, solving the problem of inconsistency between urban power distribution equipment and landscape environment, and is a special equipment combining urban refined power distribution with landscape construction.
