Description
33kv Gas Insulated Ring Main Unit
The gas-insulated ring-ring network cabinet is composed of standard functional units, which are processed by the factory, using the technologically advanced FLN36-12/24 load disconnect switch, and the excellent performance of SF6 gas as the arc suppression insulating medium. The cabinet is small in size, reasonable and compact, easy to install, simple to operate, safe and stable, and has been widely recognized in power supply systems such as 10KV or 24KV.

Our advantage:
(1). Energy saving: Fengyuan regulating capacitor changes the output reactive power by adjusting the voltage on the capacitor, so that the reactive power can be regulated smoothly. Compared with other methods, it can ensure that the capacitor is in the best condition and the energy saving effect is better.
(2). Low cost: If the old substation needs to be retrofitted, just add a voltage stabilizer between the circuit breaker and the capacitor. The original circuit breaker, reactor, and capacitor can be reused, greatly reducing the cost of retrofitting
(3). Maintenance-free: When traditional circuit breakers and contactors are switched, switchgear and capacitors are often damaged due to the above-mentioned problems, resulting in high maintenance costs. Using our equipment, automatic control of reactive power output, there is no potential risk of other equipment, greatly reducing the maintenance and personnel costs of the substation
(4) Quality assurance
From raw materials to finished products, we have strict quality control procedures. An advanced testing laboratory can ensure product quality and increase our creativity. Quality and safety are the soul of our products.
(5) Quality service
Years of manufacturing experience and rich export business have helped us build a well-trained sales and service team for all customers.
(6) Fast delivery
Strong manufacturing capacity can meet urgent delivery time. About 15 to 25 working days after we receive the payment. It varies according to the product and quantity.
(7) OEM ODM and MOQ
A strong R&D team can quickly develop new products. We welcome OEM, ODM and customized orders. Choose the current product from our catalog or seek engineering help for your application. You can tell us your purchasing requirements
Usually our MOQ is 1 per model. We also produce OEM and ODM according to your requirements. We are developing global agents.
