GRO AG, a connection and installation technology specialist, has expanded its portfolio of shielded
EMC cable glands, adding an all- new version for electrically powered industrial vehicles and mobile machinery. The EVolution EMC cable gland for high-voltage applications features a high current-carrying capacity and effective 360° shielding. The entire product design is tailored to the specific requirements of vehicle and component manufacturers and cable assemblers. Evolution EMC combines the advantages of “pluggable” connections with those of cable glands.
REDUCED ASSEMBLY TIMES The new cable gland system reduces assembly times in electric vehicle (EV) production lines since Evolution
EMC cable connections are as easy to handle as pluggable connections. The cables are assembled in just a few steps: the cable lug is fed through the cable gland, the contact sleeve is fastened, the sealing insert with anti-twist protection is inserted, and the compression nut is tightened all the way. This saves time-consuming, error-prone cable shielding work in the actual vehicle assembly line. In addition, repairs can be carried out quickly, reliably and effectively because the shielding is not compromised by repeated swapping of cables, and the slotted sealing insert can be replaced without separating the inner conductor from the cable gland system.
SECURE CONNECTIONS Cable glands for high-voltage electrical systems in machines and industrial vehicles must withstand
high mechanical and thermal loads. If conventional connection technology is used, this can result in anything from inadequate EMC shielding and sealing to short circuits and, in the worst case, vehicle fires. High safety standards are required, especially for permanently installed electrical equipment with connections that are not included in maintenance routines and therefore must have a long service life. Such installations include AC converters, traction motors, PDUs and DC/DC converters – but also auxiliary drives, ancillary equipment such as air compressors, air conditioning compressors, coolers, steering pumps, fuel cells and any onboard charging infrastructure.
SPECIFIC CHALLENGES The conductors between converters and traction motors, especially, must provide reliable EMC shielding
