Terminal blocks, headers, plugs and sockets have a variety of applications in our daily lives. This article discusses the application field and working principle of HI0830520000G.

Application Field

HI0830520000G is a 7 Pole type 40000V terminals blocks applied in terminal blocks organization. It is widely used at the exit of high-voltage switchgear, container-type box and the junction box of outdoor substation for power supply & distribution. The HI0830520000G terminal blocks series complies with IEC Latinum that covers the fundamental requirements for rated voltage of 690V AC and 1000V DC, rated current of 300A, maximum short-circuit current rating up to 50KA. It also has reliable contact operation, perfect safety & anti-skid removable cover design.

Working Principle

HI0830520000G terminal blocks consist of insert, terminal board, current switching needle, insulation sleeve and base cover. The snap-in design is adopted in insert, which ensures the smooth installation of conductor and the secure contact. Also the current switching needle is used for completing or opening the electrical connection. The integrated arc suppression base cover is also provided. It can block the emission of arc and static electricity for terminal blocks protection.

The working principle of HI0830520000G terminal blocks is based on a mechanical interlock. The screw, which is moving in the block, is connecting both boards in order to close the electrical circuit. The locking mechanism of the terminal blocks is based on the use of blind and screw screws. All the contact points are tightened and connected with the screws.

The contact points are opened and closed by moving the screws. When the screws are tightened with the required torque, the connection between contact points are closed. When the screws are loosened, the connection between contact points are broken, thus isolating the power circuit.

In order to ensure high reliability and stability of the terminal blocks, special materials have been used. The terminal block body is made of high-strength engineering plastic with good insulation performance, fire performance, thermal stability and wear resistance. The contact needle used in the terminals is made of high-conductive copper with low resistance, ensuring good contact performance.

Conclusion

HI0830520000G terminal blocks is a breakthrough terminal block product with reliable contact operation, perfect safety & anti-skid removable cover design. It is widely used for power supply & distribution in high-voltage switchgear, container-type box and the junction box of outdoor substation. It can effectively block the emission of arc and static electricity for terminal blocks protection, making it an ideal choice for terminal block applications.
