his joint stack design has taken into the consideration of a bigger contact surface of the conductors in order to reduce power loss and improve cooling performance. Double headed joint bolts together with Belleville washer ensure a sufficient pressure required to secure each joint connection. The double headed joint bolt is also designed with a specific torque value whereby the outer head of the joint bolt (which acts as tightness indication) will shear off when it reaches the limit and this will prevent over tightening of the joint section.
