Solar mole repeller , solar powered mole repeller, solar mole chaser, solar rat repeller, solar rodent repeller, sonic mole repeller, garden mole repellent How about solar mole repeller? The solar powered mole and rodent repellent works in the garden, lawn. And it also works on voles, shrews, gopher, and other destructive rodents. The noise of solar mole repeller is silent to human ears, but it will prevent burrowing pests from tunneling your yard to death. The solar mole & gopher chaser produces a sonic pulse. You can use overlapping stakes to cover a larger area. This solar gopher repellent repels unwanted burrowing rodents with the strongest and least expensive power available just because it's powered by the solar. This ingenious device is environmentally friendly and eliminates the use of poisons and traps around your children and pets. Pets won't be affected by solar mole repeller, but rodents find the noise irritating and eventually move to quieter surroundings. Product description: The solar mouse repeller emits a vibrating sound underground every 30 seconds that annoys the heck out of moles, gophers, voles , forcing them to evacuate your yard. An internal ni-mh battery recharges by sunlight and powers the solar mouse repeller throughout the night. Effective for up to 600 square meter. Effective range: 600 m2 Frequency: 400 hz Rechargeable batt included: 1.2 v 600ma h ni-mh Solar panel : 2v/45ma Operation current : 6ma Weight : 0.3kg Case raw material : abs , aluminum cannulation ( 34cm).

¡¡¡¡ydq5 liquid resistor rotor starters (hereinafter referred to as starters) are the new kind of starting devices developed for improving the starting feature of large- and medium sized wire-wound ac asynchronous motors. Having solved the problems of frequency sensitive resistor starters which are high in impact current, difficult in starting and not easy to Technical characteristics 1 the starting current is low but constant without impact on power network; the starting current is no more than 1.3 times the rated current. Therefore the requirements of the heavy-load starting of motor for transformer capacity can be decreased, reducing lump sum investment. 2 it is smooth in starting, so as to lower its impact on the mechanical equipment, and the service life of the mechanical equipment and motor can be prolonged by about 30 percent. 3 it is high in its heat capacity, and it can start for 3~10 times continuously. 4 it can still start under low voltage state. Smooth start can be ensured so long as the voltage of the power network can guarantee the motor to operate normally. 5 it is simple in structure, easy to maintain. Its reliability is more superior than that of frequency sensitive, oil-soaked type resistors. Packing:wooden case Dimension: variable
