OUTDOOR PREFABRICATED
SUBSTATION (EUROPEAN) YINGMING POWER
Functions and features

◆ high-voltage switchgear, transformers, low-voltage switchgear three-in-one, complete sets of strong;
◆ high, low pressure protection perfect, safe and reliable operation, easy maintenance;
◆ less land, investment in the province, the production cycle is short, easy to move;
◆ flexible wiring program;
◆ unique structure: unique honeycomb structure double (composite board) shell solid, heat and cooling ventilation, beautiful, high degree of protection,
the shell material is stainless steel Qin alloy, aluminum, cold-rolled plate, color plate optional;
◆ various types: general-purpose, villa type, compact and other styles;
◆ High-voltage ring network cabinet can be equipped with network automation terminal (FTU) to achieve short-circuit and single-phase ground fault of
the reliable detection, with "four remote" function to facilitate distribution network automation upgrade.
