The slip ring unit combined with these junction boxes, certified for use in ambient temperatures of -40°C to +45°C, allows a throughput voltage and current of 1kV and 200 Amps respectively. As with the TX4740/TX4741, the slip ring can be combined with fibre optic rotary joints and hydraulic swivels, as required.
In 2020, the TX4740 series of Slip Ring Units celebrates its 30th Anniversary in operation so is a field-proven product, suitable for winch and ROV applications.

Trolex Engineering have recently expanded the TX4700 Series of products to allow the TX4705 and TX4707 to be used directly with the TX3700/3701 Exd Connectors.
The slip rings are certified for use in ATEX and IECEx hazardous areas with an ambient temperature of -20°C to +55°C, allowing direct connection using plug-and-play technology.
Fitted with the connectors, the TX4705 has a maximum current throughput of 100 Amps, allowing up to 20 Amps/ring. The TX4707 has a maximum current throughput of 16 Amps, fitted with 2 x 8 Amp Rings. The voltage of the units is governed by the certification of the connectors. If fitted with TX3700 Connectors the voltage is limited to 240Vac/300Vdc, or fitted with TX3701 Connectors, the voltage is limited to 1500Vac/2000Vdc.
Trolex Engineering have been designing and manufacturing both explosion protected and weather protected slip rings for over 40 years. From small, low power slip ring units, through to large, high power slip rings; tried and tested in a range of arduous environments, offering both standard and bespoke products to suit any application.

Trolex Engineering have recently introduced the TX4782 Electrical Slip Ring Unit to their range, certified for use in IECEx hazardous areas, to IEC 60079-0, IEC 60079-1 and IEC 60079-7 standards, for use in FPSO applications.
The electrical slip ring has a throughbore of 760mm, allowing the passage of hydraulics, pneumatics or product pipes, with a height of 2.1m. Rated up to 500Vac with a maximum throughput current of 2010 Amps, it allows the transmission of both power and signals. The slip ring has been certified for use in an ambient temperature of -20°C to +45°C and is manufactured from 316L Stainless Steel.
The slip ring is fitted with junction boxes for connection from both the rotor and stator, allowing easy installation on-site, without the weight of heavy cables. In addition, all maintenance can be done via removal of covers fitted to the unit to access the internal elements.

Trolex Engineering have recently launched a Manually-Operated Cable Reel as part of their TX4920 Cable Reel Series.
The Cable Reel, which can be fitted with either a Weather Protected TX4845, or an Explosion Protected TX4705 Slip Ring, is suitable for temperature limits of -20°C to +45°C. With a ring current of 20 Amps and maximum voltage of 600V, the cable reel is suitable for a maximum speed of 100rpm with an IP65 rated enclosure.
The length of the cable/hose can be adjusted to suit the specification and the external material can be made in a choice of aluminium, 316 stainless steel or carbon steel with epoxy paint system.
Other options include a fluid/gas swivel, cable guide, bump stop, protective covers, special paint systems or colours and a higher current.
