1.  Product description
HVD8 /LW8-40.5 type outdoor high-pressure sulfur hexafluoride circuit breaker is three-pole ac 50 hz, outdoor high voltage switch equipment, applicable to 40.5 kV power transmission and distribution system control and protection, can also be used to contact circuit breaker and movable capacitor group.
Standard: IEC 62271-100.
Certification: ISO9001-2015
Operation: Energy-storage Type
Installation: Fixed
Arc-extinguishing Medium: SF6
Speed: Normal Type Circuit Breaker
HS Code: 85353000

a.        The circuit breaker is outdoor small ceramic column structure, which equipped with CT14 spring operation mechanism; mechanism and main part connected with simple installation. It has features of convenient adjustment, reliable operation, suitable for frequent operation; mechanism service life more than 3000 times;

b.       Adopt air-compression arc-extinguishing structure, with strong breaking capacity, 40kA total breaking times up to 12, which is the highest in China:

c.        Reliable sealing performance. Adopt import seal; dynamic seal adopts "V" type sealing ring with spring pressure compensation structure; the transformer secondary wiring board matched by cooperative enterprises, to ensure the annual leakage rate less than 1%,

d.       Inner current transformer adopts micro crystallizing alloy high magnetic materials, with accurate class up to grade 0. 2 or grade 0.2S. According to users' needs, it can be matched with 12 transformers, to meet the load line of 50 km without restrike.
