Trolex Engineering have introduced a new winch slip ring to the TX4740 Series. The TX4741 Slip Ring Unit is certified both ATEX and IECEx and has a cover diameter of 142mm.
The unit is of 316L stainless steel construction and can be combined with both single and multi mode fibre optic rotary joints. The maximum voltage is 4.5kV, with a maximum current throughput of 400 Amps, excluding earths, screens and neutrals. Each ring has a maximum throughput of 40 Amps, but rings can be paralleled if a higher current transfer is required.
The TX4740 Series is proven in the field, with the first unit being supplied back in 1991. Alternatively, if you require this diameter slip ring but for a safe area application, check out the TX4820 Slip Ring.
