During 2015, Trolex Engineering developed 4 new products covering a range of applications including winches, cranes and FPSO’s.
The TX4707 was the first to be added to our range. Intended for space-limited winch applications, the slip ring is only 95mm long in total, with a 53mm cover length, containing 2 rings rated at 8 Amps/2000V per ring. Conforming to the requirements of both ATEX and IECEx standards, the unit is capable of operating in a wide range of temperatures, from -40°C to +60°C, to suit the application.
Next up, was our TX4714. This slip ring is intended for smaller crane applications where only a small number of power and signal rings are required. The maximum supply voltage per ring is 100 Amps/750V, with a maximum throughput current of 420A (excluding earths and neutrals). Again, this slip ring conforms to the requirements of both ATEX and IECEx standards, and can be used for power, signal and I.S. circuits.
The next slip ring to be added to our range was again for crane applications. The TX4816 slip ring is a weather-protected, is individually rated up to 770V/100 Amps and may be used for power, signal and I.S. circuits, with a maximum total throughput of 1166 Amps.
Last but not least, the TX4789 Slip Ring was developed for use on the swivel stack of an FPSO. The slip ring contains 40 slip ring circuits, rated up to 500V ac/250 Amps, with a 10 Amp maximum current on each individual ring circuit. The unit conforms to the requirements of IECEx standards, and is capable of operating in temperatures of -20°C to +50°C.
Trolex Engineering will be exhibiting at Oceanology International from 15-17 March 2016, at the Excel, London.
Our technical team will be on stand to advise on any queries you may have. We'll be on Stand R371 with a range of products including the TX4815 Slip Ring Unit, the TX4740 Slip Ring Unit and the TX4700 Series.
Fibre Optic Rotary Joints are the optical equivalent of the electrical slip ring. It allows uninterrupted transmission of an optical signal while rotating along the fibre axis. A FORJ’s only function is to provide connection between two or multiple fibre cables whilst allowing free rotation between them. Therefore, it is critically important to ensure that the device has low insertion loss, small insertion loss variation (wow), and high return loss (a measure that characterises the amount of reflection a FORJ generates).
Combined with electrical slip rings, FORJ’s add a new dimension to traditional rotary joints. FORJ’s can be combined with proven Trolex Slip Rings to future-proof systems allowing ample bandwith to the end user.
A Slip Ring is an electrochemical device which allows the transmission of power and electrical signals from a stationary to a rotating structure. Slip Rings can be used in any electromechanical system which requires unrestrained, intermittent or continuous rotation while transmitting power and/or data. It can improve mechanical performance, simplify system operation and eliminate damage-prone wires fixed/hanging from moveable joints.
The Slip Ring’s function is to make one or more continuous electrical connections from points in a stationary section to points in a rotating section.
Trolex Engineering have 40 years experience in engineering, design and manufacture of Explosion Protected equipment and rotary solutions. All design and manufacturing is carried out at our 2 offices and workshops in the UK.
This is where the detailed design and development of the product’s form starts. The main tool for design and development is CAD – from a simple 2D drawing to a 3D model. This covers both mechanical and electrical. Once the design is verified, the bought-out components are sourced, with the aid of procurement systems.
Engineering is the application of science for finding solutions. Design is the creative expression of this knowledge…
Once the design of the product’s components is complete, the method of manufacturing is defined. The raw materials are taken through to final components, inspected and passed through to assembly.
Final components are fixed together to produce a final assembly before being passed through to test. A good assembly process can increase efficiency and quality, using different techniques and methodologies.
Within all the processes above, we use the problem-prevention method, concurrent engineering, providing better and more immediate communication between departments.
TEST & DESPATCH
All our products are tested to stringent safety standards prior to despatch, including tests such as continuity, dielectric & insulation resistance, volt drop, torque, dimensional checks and temperature transmission.
The IECEx Scheme, The International Electrotechnical Commission (IEC) System for global certification to standards for electrical equipment in hazardous locations, plays an important role in the global certification of hazardous location equipment. The Scheme seeks to simplify and advance the export of equipment through its harmonized international standards, facilitating global trade and international growth in hazardous locations like oil and gas sites.
It is a certification system which verifies compliance with IEC international standards relating to safety in hazardous areas. It covers equipment, service facilities and the competency of personnel. IECEx provides an internationally accepted means of proving compliance with these standards and means products can be supplied to the market without the need for additional tests.
All our TX47XX range of products are all certified to IECEx Standards. The TX4799 FPSO Slip Ring was our first IECEx-certified slip ring, which was approved in February 2008.
In Great Britain, the requirements of the Directive were put into effect on 1st March 1996, through BIS Equipment and Protective Systems Intended for Use in Potentially Explosive Atmospheres Regulations 1996 (SI 1996/192).
Since 1st July 2003, it has been mandatory under EU Law that all equipment for use in a potentially explosive atmosphere must conform to specific safety standards.
