LY-12 gas insulated switchgear series is a compact metal-sealed
switchgear system for 10KV power distribution system. The
switchgear is uniquely flexible due to its expandability, enabling
full and semi-modular combinations.The stainless steel gas chamber
of the LY-12 gas insulated switchgear equipment is filled with
SF6 gas, which completely seals all the live parts and the switch,
and isolates them from the outside world. This fully-sealed
structure keeps the internal switches and live parts from being
affected by changes in the external environment, ensuring the
reliability, safety and maintenance-free nature of the
equipment.The basic module scheme forms are: C, F, V, D, De.The
code description is as follows:C: Two-position load break switch
unit with earthing switchF: Load break switch-fuse combination
moduleV: Vacuum switch module with earthing switch and two-position
load (isolating) switchD: Cable connection module without earthing
switchDe: Cable connection module with earthing
switch Structure Working Conditions1. Ambient air
temperature: upper limit +40 °C lower limit -40 °C;2. Air relative
humidity: the daily average is not more than 95%, and the monthly
average is not more than 90%;3. Altitude ≤ 1500 meters (under
standard inflation pressure);4. The seismic intensity does not
exceed 8;5. Places without fire, explosion, serious pollution,
chemical corrosion and severe vibration. Special
conditionsManufacturer and end user must agree on special operating
conditions that differ from normal operating conditions.If
particularly harsh operating environments are involved, the
manufacturer and supplier must be consulted.When the electrical
equipment is installed above 1500 meters above sea level, it should
be specified so that the pressure can be adjusted during
manufacture. When this pressure is adjusted, the life of the
switchgear itself has no significant effect.Main technical
