Product Introduction

YBW-35KV Outdoor box-type substation  is a complete set of products that assemble voltage switchgear, transformer and low-voltage power distribution equipment into one body. As a power transformation and distribution equipment for urban buildings, living quarters, small and medium-sized factories, mining and oil fields, etc., it has strong complete sets, small size and compact structure, high reliability, small on-site installation workload, short installation height cycle, and Portable and other features. Appropriately change its appearance and color to adapt to the environment, and can also play a role in beautifying the environment.A set of equipment.
Our YBW-35KV Outdoor box-type substation consists of high voltage switch room, low voltage switch room, relay protection room and transformer room. The shell of high-voltage switch, low-voltage switch room and relay protection room can be made of aluminum alloy plate, steel plate or composite
board making. The surface of the aluminum alloy plate is anodized to enhance the corrosion resistance of the aluminum alloy plate. The steel plate and steel structure parts are all treated by phosphating, and the composite plate has the characteristics of bright color and beautiful appearance, heat insulation and flame retardant. The transformer room does not have a closed shell structure but a high safety net cover, which is not only conducive to the ventilation and heat dissipation of the transformer, but also ensures the safety of people and equipment.
High-voltage switch room HV high-voltage switch room can be equipped with JYNI-35. KYNI0-35 switch cabinet or 35KV load switch. 35KV incoming and outgoing cables can be freely selected by users for overhead cable mode. Low-voltage switch room LV: When the low-voltage side is 10KV, the low-voltage switch room can install X(GN2-1. KZNI-12. KYNI-12 switchgear, HXGNII-10F. HX(GN26-10(F) ring network cabinet. When the low side is 0.4KV, install DWI5T series, ME series, M series, F series frame type circuit breaker and D220 series, CM series, H series, S series in the low voltage switch room (generally do not make low voltage switch cabinet to save space) Series molded case air circuit breakers.
