Product Details

General:

Rockwill providing with Designing & manufacturing for Prefabricated substation with outdoor SF6 switch (switchgear) station, completed moible substation:
Prefabricated outdoor SF6 switch station for the exchange of 50Hz, rated voltage 12kV, 24kV, 40.5kV power distribution 630A rated current distribution network of secondary structure. Can be used as urban residential areas and factories mainstream electricity supply program. The opening and closing the main switch by the use of SF6 gas-insulated and insulated the entire load interrupter switch, with a number of international patent technology. First imported into the round of insulating material made of branches of cable connectors, protection grade can reach IP68. Opening and closing the main use of 304 stainless steel outside the box and then the second spray process.
a. anti-filthy, anti-corrosion;
b. full-confined, all-insulated, maintenance-free;
c. ring network with SF6 load switch-type inflatable counters;
d. touch with silicone rubber cable plugs;
e. to meet local user groups focus on electricity supply;
f. with ordinary cable distribution boxes all the characteristics;
g. institutions can be allocated to electric operation;
h. can be set aside for distribution automation CT, PT interface.
The whole insulation, all sealed, anti-Gel; into line with three-position switch or circuit breaker SF6 load; into the round about at home, safe and reliable; can be allocated

to electric operation agencies, and set aside automation interface; landscape design; wiring convenient and reliable, into the round can be equipped with anti-type fault indicator.

YB() series products is a kind of set of equipment which assembles the MV switch apparatus, transformer, LV distribution equipment together according to fixed connection scheme. This series substation is suitable for neighborhood unit, hotel, large-scale work site and high building that the voltage is 12kV /24kV/36kV/40.5kV, the frequency is 50Hz and the capacity is under 2500kvA.

Main Designation Characteristics

The crust of the substation is designed according to the foreign advanced technology and physical reality. We provide many kinds of crust material such as aluminum alloy steel composite stainless steel board and non metal material(glass fiber).

The HV side use charge switch or vacuum circuit breaker. The transformer could be oil type hermetically-sealed type and dry type.

The proof of the box is double layers structure and between the layers is filled with foam. There are independent boards in HV and LV room, and in the transformer room will install auto thermal controller heater and cooling equipment.

Note: we offer special customized products according to client’s requirement.

36kV/40.5kV Prefabricated Substation Characteristics

This type substations are the HV side 40.5 kV, LV side 0.4-12 kV and 3 phase outdoor completeequipment .It is wide used in cities , towns ,factories and oil fields, wharfs etc. It is also used insome construction sites. The characteristics are small volume, convenient installation, low cost,high automation safe and reliable operation. Substation is combined with HV switch room,LVswitch room, relay room and transformer room.
