5 Cables Dim (copper): Φ10mm 23m Material: copper & PVC Accessories Base,Wire,wire Tighting Tool, Anchors of Base, Anchors of Wire,nut & washer & bolt suitable for installation Packing PLYWOOD CASE Price USD26060 FOB Qingdao Product advantage: 1. Generator: our generator with cooling function. It can not burn out when the wind is very strong. 2. The wire package in the generator is made of copper wire which can resist 180 heat. High insulated performance, high magnetic permeability, high generating efficiency. 3. The magnetic sheet is Neodymium iron boron not ferrite. Neodymium iron with longer life time than ferrite and not easy to demagnetize. The stator is made of 470 silicon steel sheet. Not iron sheet. 4. Blades: streamline shape tree pcs FRP blades. Unidirectional fiber fabric, use of epoxy rein mold made by hand. Not hollow it is inner foam. Low noise, no need to adjust and good quality of balance, no shaking. Strength, fatigue resistance. 5. Controller is solar and wind hybrid, have manual brake button. 200% immediate protection foundation. 6. Inverters are pure sine wave, not square wave or vehicle-bone inverter. The material of tower is steel tube, PET paint, anti-decaying, antiseptic, rust-proof. Remark: 1. Delivery time: 20 days 2. Payment: T/T 50% deposit and balance after receive the copy of the B/L. 3. Min order quantity: 1 set 4. Container capacity: 40 container 3 sets 5. Packing: ply wood case 6. Technical parameter can be adjusted as your demand. 7. Guarantee: The guarantee for the system is 1 year from the date of purchasing (no-done by man or majeure).
