Rail Terminal mainly puts into use on track and railway system. Technicians usually use it when they are doing some security detection. Unlike the traditional terminal, the main material of rail terminal is made of copper and equipped with silicone sleeve or spring as the outer layer. The choice of sheath entirely depends on customers’needs. The reason why to equip with silicone sleeve or spring as the outer layer is because of the function of silicone sleeve and spring can play a role in shock resistance. In addition, it can be used under high temperature. Namely, this type of composition provides security to a certain extent. Moreover, the crimping method of traditional terminals is easily to break wires. However, this kind of innovation product does not need to crimp anymore and perfectly avoid the situation of break wires. Up to now, rail terminal has already been used into a half of China and gradually spread out to the rest of provinces.
