   Working environment of wind energy equipment is different, for example, in northern cold region, rubber seal products must protect themselves from blowing sand, corrosion resistance, low temperature rubber, while sealing products used in offshor must face chanllenge of salt fog corrosion, heat aging resistance, etc.

  At present, the main sealing problem faced by wind power equipment is lubrication system design. Bearing isolator (bearing protector), as an improving replacement of rubber seal and labyrinth seal, is a compound labyrinth seal with unique design structure, which is composed of dynamic and static rings. Static rings open with return oil groove, and there is no friction between static and static rings, which can truly achieve zero leakage of rotating equipment.Dynamic and static ring complex external section of labyrinth channel, and a drain hole in the bottom, can stop the dust, vapor, mist, such as intrusion, protection level to IP66. Bearing isolator by excellent corrosion resistance and heat dissipation of tin bronze processing and become, with fluorine rubber material static seal, service life can reach several decades, and no maintenance.Compared with the traditional rubber seal or labyrinth seal, the bearing isolator is a kind of seal device which is really designed for wind power and has a long lasting protection, which greatly improves the operation stability of the equipment.

  - split-type structure design, which does not require disassembly of equipment when installed onsite, can be used for onsite replacement or initial installation of equipment.

  - Bearing isolator equipped with superconducting fiber shaft grounding technology can well solve the electric discharge damage of the bearing caused by wind power generator shaft voltage
