Jinpat Electronics 

<h3 >Overview</h3><p ><span >With the extensive application of the mechanical equipment and automation equipment technology upgrade and enhanced functionality, a growing number of machinery and equipment adopted conductive slip ring. Because of the mechanical equipment used in the conductive slip ring, it can help improve the performance of the wire transfer for mechanical equipment operation efficiency greatly, so a lot of industry of machinery are using conductive slip rings to improve operating efficiency. But the slip ring requirements for each machine are different, because each mechanical work environment is different: current, voltage, different levels of protection, rotation speed, etc.; which also contributed to the emergence of various models and types of conductive slip rings. For example, </span><a href="http://www.slipring.cn/products.php?bc=41">high current slip ring</a><span > is often used in communication equipment and other equipment to avoid the system in operation. And to ensure a smooth electrical connection, transmission cable will not be broken due to twisting through the use of a conductive slip ring. So how do we design a high current conductive slip ring? </span></p><p >As the transmission of a large current device, the primary consideration is the contact material, installation and brush contact, to ensure that the high current conductive slip ring is in the working state of contact reliability and service life. Secondly, the installation to ensure the normal performance of conductive slip ring. As the high current conductive slip ring needs to be used in seawater environment, its shell material must use corrosion-resistant stainless steel. The main components of the conductive slip ring's body and brush: for the key components of the conductive slip ring, it uses a surface of thick gold as the electrical contact material; the brush is mainly sheet spring brush, linear spring brush, and a brush made of metal and graphite block (which produces high current density and minimal wear, but the resistance is large). The flake spring brush is more suitable for high-speed environment. The linear wire has excellent elasticity and electrical conductivity.</p><p >The final brush combined the characteristics of various kinds of brushes. The insulator can use PBT as an insulating material, PBT has excellent dielectric properties, chemical resistance, fatigue resistance and lubrication performance. In the aspect of mechanical structure, it is necessary to consider the characteristics of the large current of the conductive slip ring. You also need to fully consider the design of electrical insulation, installation, and maintenance performance and so on. </p><h3 >Advantages </h3><p >First, the high current conductive slip ring's advantages: </p><ul ><li >the choice of top imported graphite alloy</li></ul><ul ><li >the current can be up to several hundred amps</li></ul><ul ><li >compatible with the data bus protocol</li></ul><ul ><li >long life, maintenance-free, no lubrication </li></ul><ul ><li >360° continuous rotation transmission power or data signal</li></ul><ul ><li >compact appearance. </li></ul><h3 >Options</h3><p >Second, the high current conductive slip ring's options: </p><ul ><li >the number of channels</li></ul><ul ><li >the signal and power can be individually or mixed transmission</li></ul><ul ><li >current, voltage</li></ul><ul ><li >the length of the wire</li></ul><ul ><li >connecting terminals</li></ul><ul ><li >protection class</li></ul><ul ><li >outlet direction.</li></ul><h3 >Applications</h3><p >Third, the high current conductive slip ring's typical applications: </p><ul ><li >industrial machinery - machining centers, rotary table, lifting equipment towers, reel round, test equipment, and packaging machinery; </li></ul><ul ><li >magnetic actuator, processing program control equipment, turntable sensors, emergency lighting, robots, radar and so on; </li></ul><ul ><li >Manufacture and control of equipment. </li></ul><p >The high current conductive slip ring with its unique contact and connection type, excellent electrical contact performance, long service life, flexible structure and comprehensive performance can reach the level of similar foreign products. Jinpat can customize different diameter of axle size, different specifications, current size, number of channels, speed, protection level and other parameters of the slip ring according to customer requirements, which can be widely used in security, automation, electricity, instrumentation, chemical, metallurgy, medical, aviation, military, ship, transportation and other electrical and mechanical equipment. </p>
