Central collector
Product Introduction:
K530 central collector ring is mainly used in the power supply circuit of tower cranes with AC 50Hz (60H2), rated working voltage up to 380V (440V), and rated working current up to 300A. When the tower crane rotates, it prevents the cable from twisting due to rotation, achieving a protective effect.
Structural features:
The shell components of this product are made of stainless steel plates bent into shape, which is beautiful and solid, with high waterproof and anti rust performance. The internal carbon brush combination is accurate and can fully meet the rotation requirements of tower cranes.
