JSZV18-10_6BR voltage transformer
JSZV18-10, 6BR voltage transformer is specially designed for XGW-12 outdoor AC fixed industrial metal-enclosed switch. The primary winding of this type of voltage transformer is protected by a fuse, which provides 100V measurement voltage and 220V operating power for relay use.
structural features ：
The transformer is one of import electrical appliances in electric system. It’s similar to power transformer and also used to transformer voltage or current in the circuit. However, transforming voltage and current by power transformer aims at transferring electric energy while transforming voltage and current by transformer aims at measuring and monitoring voltage or current in the circuit. Generally, power transformer owns large capacity as well as large change difference of voltage or current. While transformer owns small capacity as well as smaller change difference of voltage or current. In measuring circuit. The transformer that transforms current and supplies electricity for current meter and relay is called current transformer. The transformer that transforms voltage and supplies electricity for voltage meter and relay is called voltage transformer.
The current transformers are in accordance with GB/T20840.1. 3 and EC61869-1.3standards
Rated insulation level 12/42/75k. 7.2/32/60kV
Rated frequency 50Hz or 60Hz
Note: 1.If the required parameter is beyond the above range, it can be discussed and confirmed with us.
2.Typе of the matched fuse is XRNP□ -12.72, 0.2. 0.5A. 50kA.
3.The voltage class of the attached cable head is 20kV American 200A.
Applicable working conditions：
The altitude does not exceed 1000m. (If used in highland areas, please specify the altitude).
The ambient temperature does not vary by more than 5°C to 40°C. (if required, please specify in the order).
Common products can be used in areas with relative humidity not higher than 85%.
There is no gas, steam, chemical sediment, dust or other explosive and corrosive media that seriously affect the transformer.
No serious vibrations or bumps. anyone.
When the primary current passes through the current transformer, the secondary winding is not allowed to open circuit,
Otherwise, high pressure will be generated, which will affect the performance of the product.
The secondary winding of the voltage transformer is not allowed to be short-circuited. Otherwise it will burn the transformer.
The repeated power frequency withstand voltage test of the primary winding shall be performed at the specified test voltage.
80% of the value.

We keep kep parts of semi-finished products of RMU in stock usually.
The CGIS1580 current transformer is a high-quality product that is perfect for a wide range of applications. Its compact size and low weight make it easy to install, and its accuracy and precision ensure reliable performance.
An SF6 Gas Insulated Ring Main Unit (RMU) is a type of electrical switchgear that uses sulfur hexafluoride (SF6) gas as an insulator. The SF6 gas is contained within a sealed chamber, and the electrical components of the RMU, such as the switchgear and circuit breaker, are also enclosed within this chamber. The use of SF6 gas as an insulator allows for a compact and lightweight design, which makes it ideal for use in restricted spaces and for underground applications.
