â? 1ã?�PRODUCT BRIEF INTRODUCTION: QRA series products are designed and developed based on Chinese national military standard GJB773A-2000, referred to American military standard MIL-W-22759/32~35, MIL-W-2275/46, and combined with RAYCHEM products. The insulation of this product is made of cross-linked high molecule material after irradiated by high energy electron beam, its special structure solves many problems encountered by aviation wires and cables, including size, weight, flame resistance, durability, mechanical performance and resistance to chemical environments. It has high and low temperature resistance, light weight, no heat shrinkage, excellent mechanical toughness, anti-salt spray, anti-hot flash and excellent anti-high energy radiation, can provide reliable service in harsh environments. The product is easy to use, save space and its superior performance, meet the aviation and mechanical equipment on the space and weight requirements. After tests, all the performance in line with MIL-W-22759/32 ~ 35, MIL-W-2275/46 requirements , the products are widely used in aviation, ships, missiles, aircraft, electronics and other military fields. Since the launch of the QRA series of high performance transmission wire, it has been batch used in a number of key products. According to the users to reflect, it can replace foreign similar products, breaking the long-term foreign companies on China's high-performance aviation wire monopoly. â? 2ã?�APPLICATION: The product is used for information and energy transfer between aerospace, aviation, ships, electronic equipment, military vehicles and other series of environmental electrical appliances.
