4. It can be equipped with ZN63A-12 series or imported VD4 series vacuum circuit breakers produced by our company. It has wide applicability, high reliability and long-term maintenance-free.
5. The hand truck is set to work and test position, and each position has positioning and display devices, which are safe and reliable.
6, all types of handcars according to the modular building block changes, to ensure that the same specification car can be freely interchangeable, different specifications of the car can not enter.
7. The handcart is transported by a special carrier, which is light and flexible.
8. Up to 9 single-core cables can be installed in the cable compartment.
9. Highly reliable interlocking device fully meets the requirements of “five defensesâ€.
10. Each pressure chamber has a pressure relief passage to ensure personal safety.
11. The door is equipped with an observation window to observe the working condition of the indoor components.
With Push-in connection technology, you can connect conductors easily – both directly and without tools, insert forces reduced by 50%. it is suitable for various applications. Insert rigid conductors or conductors with ferrules from 0.25mm² into the conductor shaft.The contact spring opens automatically and provides the required pressure force against the current bar.
When installing smaller conductors from 0.14mm², use a standard screwdriver to push the orange button and actuate the contact spring.
Push-in Connection have test and passed various certificates. For example, Vibration resistance in accordance with railway standard DINEN50155,shock and corrosion resistance in accordance with current shipbuilding registers.
