Blades:

FRP, (Fiber Reinforced Polymer) acronym, the existing CFRP, GFRP, AFRP, BFRP so on.

Chinese in FRP refers GFRP. FRP composite material is a fiber material of the base material

according to a certain mixing ratio, after a special extrusion die, drawing the formation of

high-performance materials.Since the resin used in different varieties, so there are glass fiber

reinforced polyester, glass fiber reinforced epoxy , phenolic FRP said. Light and hard,

non-conductive, high mechanical strength, recycling less resistant to corrosion.

the inverter:



1.digital design, simple structure, powerful, stable and reliable
2.using annular isolation no-load loss of transformer, inverter with high efficiency

It can start generating power under very slow wind speed condition, wind speed

   3m / s ~ 25m / s are the generating range. More than 1/3 of the time in advance of

   the general wind power generation, the power generation efficiency has increased

   of 30%, which greatly improves the utilization of wind energy.

Mute design multiple protection 

   Super mute double design, with FRP rotor blades and airfoil, it's toughness strength

   is greatly improved, lighter weight, stronger tensile strength. Run more smoothly,

   greatly reduced the occurrence of crashing.
