Recloser RCW+
RCW+ type auto recloser is a high performance switchgear sealed with SF6 gas. Which is IP67 class switchgear.
RCW+ type auto recloser is DESIGNED For using very important field like key electricity supply points like: gas/oil/mine field, hospital/government/military area, important building etc.
RCW+ Auto recloser is equipped with a manual closing solution which is patent design according to the existing brands recloser problem, like ABB, Schneider, Eaton,Siemens, Hubbel,Noja,Jinkang,ect, these listed brand only offer a normal solution recloser which design cant provide with solution for manual closing with elctric power.
RCW+ auto recose is a fast switching switchgear, standard configuured with magnetic actuator and manual closing and opening/locking device, Max 6 voltage sensors.
RCW+ auto recloser is full complied with standard IEC62271-111, ANSI/IEEE C37.60.
RCW+ auto recloser is Offering:
Voltage Rating: 15kV- 38kV
Current Rating: 630A-1250A
Short circuit breaking: 16kA,..25kA
More informations pls go to study RCW+ manual.
· Recloser feature a)Outline of recloser:
The RCW series vacuum recloser is mainly combined with integration terminal, current transformer, permanent magnetic actuator and it's recloser controller.
b)The recloser tank feature:
The Vacuum recloser tanks are manufactured from 304# grade stainless steel and are powder coated a light grey colour. Whole recloser IP67 protection class, equipped with a auxiliary plug to connect with recloser controller by control cable, Diameter Max22mm, 6 M length (8M for special).
It's can performance serve more than 20 years long term under heavy duty circumstance.
· Main new advantages of RCW High reliable manual opening device High reliable manual closing device
Visible ON/OFF indicator IP67 class waterproof plug connector
Primacy incomer terminal (directly connect to interrupter reduce power lost) Current sensor (external modular design easy for quality control and maintenance) Accuracy: ±0.5% Ratio:800/1
Internal Voltage sensors incorporated within the vacuum interrupter module. Accuracy: ±0.2 % Voltage Sensor, Ratio:500/1 or 1000/1.
It's equipped with two voltage sensors, one for measuring the voltage of incoming side, and another one for measuring the voltage of outgoing side.
