Product Description:


The circuit breaker be superior to domestic like products. It is the first choice of 550KV power system;


 LW30-550(T)/Y5000-63 high voltage SF6 tank-type circuit breaker is invented by our company so as to satisfy the demand of extra-high voltage(EHV) distribution device’s high parameter, high reliability, easy running. The circuit breaker

be superior to domestic like products. It is the first choice of 550KV power system;

The main characteristics:

Good breaking capacity to fault.
 The circuit breaker uses the principle of self arc-extinguish. The spout is designed by simulated analysis. It has the excellent performance of arc-extinguish. The short-circuit breaking current is 63KA, and the arcing time is short. The operation noise is small.

Long electrical life
 The arc-extinguish chamber owns lots of patent technology. The spout and arc contact uses new arc resistant material. The main contact uses new structure,and the insulation tank between fractures uses new process. Free-maintenance in the condition of continues breaking 63KA short circuit current 20 times.

The high insulation level

The arc-extinguish chamber is optimally designed by Ansys.It owns lots of patent. The furnace of electrode uses electrostatic coating technology. The insulation level has reached the highest standard of GB1984 and IEC62271.

Great peak current
 The contact of main conductive loop uses new Copper alloy materials and spiral spring contact and so on with small volume, good conductive performance, high dynamic reliability. It can run with 5000A current.

High mechanical reliability
The circuit breaker is equipped with ABB HMB-8 spring operation structure with high reliable operation. Free-maintenance in the condition of continues 10000 times operation.

The main structure:

Arc-extinguish chamber
It is designed according to auto arc-extinguish principle.

Q:High and low voltage distribution equipment
High voltage distribution equipment: high voltage fuse; high voltage isolation switch; high voltage load switch; high voltage circuit breaker.
Q:Rural high voltage transmission line equipment ownership
the transformer can be what, look at the role of electrical appliances can be
Q:AC distribution equipment including distribution box
so there will be in the power distribution cabinet a reference line and a zero line selection of single-phase 6A can switch.
Q:Transmission and transformation equipment
Because of the need to change the current in the process of transmission, so the current transfer is called power transmission.
Q:An introduction to the interpretation of flexible AC transmission systems
synchronous compensator (STATCOM), reactive power distribution is mainly used to improve the system, to adjust voltage and improve the voltage stability of the system;
Q:What is the power equipment in the distribution room?
which is mainly used for the distribution of the electric energy of the low-voltage users, and the utility model is provided with a medium voltage input line (a small number of outlets)
Q:Power distribution equipment should be prepared before the blackout?
Before the power failure, the person in charge or the electrical appliance technician should fill in the work order.
Q:DC transmission equipment
Power supply operation of power plant and substation in nowadays are used in DC power supply, it provides power for the control of the load and power load and DC emergency lighting load, is the foundation of modern electric power system control and protection
Q:What are the general requirements for working on distribution equipment?
Distribution equipment including high voltage power distribution room, substation, power distribution transformer platform, low voltage power distribution room (box), ring network cabinet, cable branch box] outage maintenance,
Q:Transmission system and distribution system
Simply put, you can distinguish between the end of the cable to the use of electrical equipment (motor, power box) is the distribution system to the substation, transformer is the transmission system
