Low voltage grid connected cabinet

Product Overview

ZYBWG low-voltage grid connected cabinet is an important component for undertaking centralized inverters and step-up transformers or AC combiner and step-up transformers.

The incoming line of this photovoltaic grid connected cabinet adopts circuit breaker input or direct input, and the output adopts circuit breaker or load isolation switch. The busbar is connected with electroplated or purified busbar and provides secondary lightning protection. The highest rated voltage of the system is AC690V, and the protection level is IP40 indoors and IP65 outdoors; The cables for secondary measurement and control include cables with a current greater than 2.5mm2, cables with a voltage greater than 1.5mm2, and cables with a control voltage greater than 1.0mm2. The measuring current transformer is a 0.5 level current transformer, and the measuring current transformer is a 0.2S level current transformer. Related functions can also be added according to customer requirements.

This product adopts professional electrical design and component selection, making the internal structure of the cabinet safe, simple, beautiful, convenient for on-site wiring and maintenance, and ensuring long-term stable operation of the equipment.
