Nanchang Ou main products are: solar lights, solar garden lights, solar lawn lights, solar wind hybrid street light series; a variety of LED light sources, solar PV modules, batteries, controller; various lampposts, patio poles, waterproof box and supporting the use of flip-flops, light control when the control switch and other electrical products. Solar lighting products are green, safe, energy-saving features. Winter solar street concrete attention to the problem of concrete construction in winter winter construction project should be organized well in advance planning and preparation should be taken to prevent snow, frost and other measures for the materials and facilities in advance. During the winter, when the construction, the use of Portland cement or Portland cement concrete compressive strength of the preparation to reach 40% of the design strength of not less than 5 MPa and in Hangzhou, not cold. Winter construction, fire prevention should be developed, antifreeze, anti-gas poisoning and other security measures. When pouring concrete mixed with lead gas agents, air entraining admixtures of water reducing agent to improve the Hang frozen concrete. The temperature of the material mixing concrete shall meet concrete mixture was stirred synthesize the desired temperature. When winter mix concrete 30w solar street price, not with snow and freezing aggregate clumps lights solar system, strict control of concrete mix and slump; feeding should be preceded by hot water mixer, feeding sequence: first aggregate and water and stir, stir in Canada when cement mixing time should be prolonged to 50% higher than room temperature. concrete mixture temperature should not be lower than the machine l0 ℃ park solar lights, into the mold at a temperature not lower than 5'C, transportation and pouring concrete technology Requirements: concrete transport time should be as short as possible, container transport concrete insulation measures should be. Template should be removed before concrete pouring, snow or dirt on steel, ready molding curing temperature heat storage method shall not be less than the lot; steam method of not less than 50C; thin structure shall not be less than the limited 8C Nanchang Europe Optoelectronics Technology Our main products are: solar lights, solar garden lights, solar lawn lights, solar wind hybrid street light series; a variety of LED light sources, solar PV modules, batteries, controller; various lampposts, garden bar, waterproof box as well as supporting the use of flip-flops, light control when the control switch and other electrical products. Solar lighting products are green, safe, energy-saving features. Solar street pick six tips to introduce solar street selection tips, I hope you will enjoy it. A view of the source of solar lights battery capacity. 2, take a look at the power consumption of LED and other capabilities. 3, take a look at the solar panels convert solar energy into electrical energy efficiency. 4, LED lights light brightness. 5, the poles of the extent of anti-corrosion and strong. 6, LED lamp shades and other small problems viewing. Through more than six, we will be able to see the quality of basic solar lights. However, we still recommend choosing large manufacturers, the choice of brands. Solar street lights installed solar street _ _ camphor solar street Merchants Ou Ou by Optoelectronic Technology Co., Ltd. Nanchang. Nanchang Ou Optoelectronics Technology Co., Ltd.
