7HKM-182 AIRCRAFT STARTING TROLLEY 7-HK-182 BATTERY

　　VENTURA 7-HK-182 aviation batteries are devices that first convert electrical energy into chemical energy for storage,and then convert the chemical energy back into electrical energy when in use.This product is used as a cold-start power source for aircraft and ground vehicles,as an aviation battery re-ignition power source during abnormal shutdowns while the aircraft is in flight,and as a power supply for communication and instrumentation in abnormal situations.Aerospace batteries feature a novel and aesthetically pleasing design,offering convenient usage and maintenance.The structure is well-designed,with reliable sealing that prevents electrolyte leakage and acid mist release,avoiding environmental pollution.It offers long discharge time,excellent performance in low-temperature operation,high capacity,ict resistance,vibration tolerance,and superior high-temperature performance,ensuring high safety and reliability.It maintains excellent performance in both high and low temperatures,providing exceptional safety and reliability.

　　1.The aviation battery cortment cover is made of engineering plastic ABS injection molding.This material has a low density(1.1 g/cm²),is lightweight,and possesses high strength,imct resistance,vibration resistance,excellent insulation properties,high chemical stability,corrosion resistance,and good structural stability in both high and low temperature environments.

　　2.The aviation battery separator is made of polypropylene plastic,featuring low resistance(≤0.0008Ω),high porosity(≥70%),excellent flexibility,and durability against breakage.It effectively prevents battery short circuits caused by the shedding of active materials.

　　3.The bonding agent uses battery-specific adhesives R311 and H2-1,which feature high bonding strength(tensile strength≥12.35 )and are robust and reliable;High insulation resistance(≥18,000 V/mm)with excellent stability in high and low temperature environments;The acid mist filter sheet is made of microporous polytetrafluoroethylene(PTFE),which collects the acid in the acid mist and returns it to the battery,allowing the gas to be expelled,thereby reducing corrosive damage.

　　4.The sealing between the aviation battery terminals and the battery cover employs two layers of acid-resistant gaskets as a line of defense,Additionally,a high-strength sealant specifically designed for batteries is injected as a second line of defense,completely preventing leakage of battery electrolyte and ensuring reliable sealing.The connection and sealing between individual battery cells employ a concealed embedding connection structure,The inter-cell connection strip is positioned below the surface of the battery cover,and then encapsulated in the recessed groove of the battery cover using a high-performance battery-specific sealing adhesive,which is then sealed within the cover's accommodating slot with a specialized high-performance sealing bonding agent.This design eliminates short circuits,enhances connection reliability,improves battery sealing performance,prevents electrolyte leakage,and facilitates maintenance.

　　The three models of aviation batteries—12-HK-28,6-HK-55,and 7-HK-182—produced by theindustrial complex are part of an aviation project.These products have undergone product standardization and appraisal by relevant departments and are at a domestically leading level.Rigorous testing and experiments were conducted on the three successfully produced prototype products.The test results indicate that,All technical indicators comply with the requirements of the"Technical Specification for Aviation Lead-Acid Batteries."Key performance indicators have even exceeded the required standards.The test results are satisfactory,and the product has passed the design review,process review,and mass production trial review.

　　High-energy sealed maintenance-free lead-acid batteries for aviation applications are used as high-performance battery packs in various models of domestically produced J-7 and J-8 series aircraft,as well as Russian-made MiG-21 and MiG-23 series aircraft.7-HK-182,12-HK-28,12-HK-30,6-HK-55 are high-energy sealed maintenance-free lead-acid batteries for aviation use.They truly meet the requirements of being fully sealed,maintenance-free,high-energy,and environmentally friendly.Cored to similar products,they offer advantages in reliability,stability,and safety.The product has been exported to more than 10 countries and regions,including Pakistan and Bangladesh;Domestic sales are directed to units such as the Air Force,Navy,and aircraft factories.It can significantly enhance the modernization level and support capabilities of equipment and weapons.With the continuous advancement of high-tech capabilities in the the demand for our cony's 7-HK-182,12-HK-28,12-HK-30,and 6-HK-55 high-energy sealed maintenance-free lead-acid batteries for aviation use is also expected to increase steadily.
