General Description
JLRM-12 gas insulated ring main unit switching station.In the cable engineering of 10kV distribution networkof power system,it has become a difficult problem to replace a large numberof branches in the empty lineof the original distribution network with an economic,reliable and convenient maintenance wiring mode.Theemergence of cable distribution box with switch has completely solved this problem and greatly reducedthe line failure rate with its fully insulated and fully sealed characteristics,Become the preferred equipmentfor distribution network cable engineering.Its simple,convenient and flexible connection and combinationmode makes it replace the ring main unit in some occasions;When necessary,it can be buried undergroundor immersed in water,which saves the investment of equipment and cables to improve the reliability of powersupply.It is widelyused in commercial centers,industrial parks and denseurban areas.
Product Characteristics
Characteristics of cablejunction boxwith switch:
1.SF6 fully insulated and sealed module of our company is adopted,with maintenance free design.
2.Fully insulated and sealed structure,touchable type,safe and reliable,maintenance free,small and heavy,light weight,compact structure,simple installation andconvenient operation.It is suitable for all kinds of harsh environments and meets the requirements of moisture-proof.The protection grade of SF6 gas chambershall reach IP65.
3.Small volume,easy to install and operate.
4.The plastic spraying process meetsinternational standards and is corrosion-resistant.
5.Take non-toxic,odorless and high insulation strength SF6 gas as its insulation medium,bus bar andconnection.All parts and load switches are placed in SF6 air bag to truly realize outdoor,fully insulated andfully sealed structure.The annual leakage rate of SF6 gas is less than 0.25 per thousand.The box is equippedwith SF6 gas pressure gauge,which can check the gas at any time.The body pressure can be transmitted tothe control center through RTU.
6.Fullyinsulated and touchablecable head isadopted for wiring,and the cable wiring is safe and flexible.
7.The ring main unit has perfect anti mis-operation function.
8.Be able to realize distribution network automation.
9.Service life:20 years maintenance free.
