PFISTERER TENSOREX C+

Automatic Tensioning System for Rail Systems

• uploaded by Chris Dodds | Thorne & Derrick Sales & Marketing Manager

PFISTERER TENSOREX C+ is an automatic tensioning system that uses the force of a coil spring to constantly tension the railway catenary and/or bearer cable.

The TENSOREX C+ is a patented spring automatic tensioning system which has been installed on many worldwide prestigious rail and tramway systems. It therefore effectively compensates the expansion caused by fluctuating daytime and night-time temperatures as well as the change in the seasons while keeping the tension at a constant level.

Applications

• For railways and tramways
• Best solution for portals, tunnels and platforms
• Inner-city installations where low visual impact is requested

Facts

• Units Sold: 14,000+ (Asia, Africa, Australasia, Europe, North and South America)
• Compensating Length: 450-1100 mm
• Line Tension Force: 7.5-40 kN

How it Works

By means of a support cable, TENSOREX C+ exerts a constant tension on the contact wire, regardless of any changes in length due to temperature. The special spiral spring is firmly connected to two cams on the same shaft. The degree of rotation of the shaft results in a linear variable torque/moment, which is compensated for by the combination with the variable radius of the cam.

This produces a constant pulling force over the entire device working range.

PFISTERER TENSOREX C+ | How it works?

^FContact wire = f (M/r) = const.

^FContact wire >> Force on contact line
^MSpring >> Torque/moment applied by spring (variable on linear basis)
^rPulley >> Radius of cam (variable)
lWork >> Device working range correspond to variable pulley profile length

IEC 61482-2 2018 – Get Up To Speed With The New Arc Flash Standard

Arc Flash Protection

IEC 61482-2:2018

Article Courtesy of ProGARM Arc Flash Protection & Clothing 

A new test standard for arc flash protection – IEC 61482-1-1:2018 – was introduced in May 2019, which means arc flash protective garments certified after May 2019 have to be tested under these new, more stringent conditions under the PPE regulation.

This is a result of the updates to the Arc Flash standard for garments, IEC 61482-2:2018, which was released in 2018.

This standard is significantly different to FR standard EN ISO 11612. It includes more rigorous and different requirements, and is the standard for garments to protect those at risk of Arc Flash. The latest update to the standard was in 2018 and contained a couple of important changes to the test methods with regards to the performance ratings of garments.

The new test results in a new way of rating arc flash clothing, ELIM (Energy Incident Limit), which will be used as a further arc rating performance property value and as a more stringent performance indicator of both fabric and garments.

♦ IEC 61482-1-1:2019 Live Working – Protective clothing against the thermal hazards of an electric arc – Part 1-1: Test methods – Method 1: Determination of the arc rating (ELIM, ATPV and/or EBT) of clothing materials and of protective clothing using an open arc.

ProGARM | Functional Arc Flash Clothing, Protection & PPE For Everyday Wear

As a result of this ProGARM have written a short guide to the new IEC 61482-2:2018 standard to highlight the key bits of information you need to be aware of when reviewing your PPE specification and the key terminology that you need to understand.

Choosing the right PPE for your team can be difficult and with all the standards to consider it can feel quite overwhelming. This guide aims to help people make a more informed decision about what PPE is best for you.

Taihan high voltage transition joint is applicable for jointing single core oil-filled (O.F) cable to single core XLPE cable. The 3-core oil-filled cable can be connected by using a splitter box (trifurcating joint box). The prefabricated and dry (oil-less) configuration is used on the XLPE cable side while on the oil-filled cable side conventional oil impregnated paper roll and newly adopted epoxy bell mouth is applied to complete the compact cable joint design.

Masterclass – 132kV ABB Cable Termination

By Chris Barker EHV Jointer

ABB 132kV Cable Terminations

Before we start, let us establish Chris Barker is an international class EHV Jointer conversant with the skills and techniques required for the safe jointing and terminating of cables using ABB, NKT, Tyco, Pfisterer, Prysmian, Ericsson and Nexans.

Whether you are reading this as a recruiter, jointer, friend or follower of Chris you can review his skill set in the following Photo Blog collection.

1, Stress Cone & Connector Taped Up – tinned copper mesh is carefully applied to the stress cone by the Jointer, then 5 layers of self-amalgamating tape are overlayered with two layers of PVC electrical insulation tape.

2. Ready For Insulator To Be Bolted Up – notice the highest level of care and attention is required by the cable jointer while the cable termination installation progresses, at each stage of the process the jointer is delicately padding the cable to remove any dirt, debris or particles that will potentially cause damage to the cable or accessory.

3. 3 x ABB 132kV Cable Terminations Plugged In Without Problems – next stage is to install the copper pipework and fill with insulating oil.

4. Preparation Of Semi- Conductive Screen Cut On 132kV XLPE EHV Cable – also known as “glassing”, this highly dexterous and skillful task is a key step in the EHV cable preparation process. Chris is pictured using microscope slides for cable glassing, although some jointers prefer welding glass mask inserts.

This basic staple of the EHV jointers tool kit is also complemented by the use of latest precision engineered cable jointers tools. In this application, the semi-conductive screen was accurately removed by a Hivotec peeling and stripping tool to 100mm from the actual mark, the remainder was removed with traditional glass.

Hivotec CP90 & CP130 cable jointing tools are used by EHV jointers for peeling the semi-conductive screen and for stripping the main XLPE insulation from high voltage power cables.

5. Old Cables Cut, New Cables Heated & Straightened – ready for cable terminations. ABB 132kV cable terminations with be installed horizontally, plugged in and then filled with electrical insulating oil. Although the existing cables had not suffered a cable fault the client upgraded the circuits to extend the service life of the 132kV power distribution system – cable heaters were used to provide straightening to the HV cables.

6. Taping Up Connector With Semi-Conductive Electrical Tape (3M Scotch 13 Tape) – a screw connector to a torque of 45NM is applied. Once insulator is installed the cable jointer fits a cap on the top which is then plugged in with bolts directly to the top cap. When the 132kV cable termination is completed it is filled with polybutene oil and sealed up prior to final connection to transformer.

7. 132kV Cable Termination Plugged-in & Filled – ready for final connection the 132kV cable termination is installed to the transformer side and insulated with oil. The connection is made via a flexible section of copper braid bolted to the cable termination inside the 132kV transformer.

8. 132kV ABB Cable Termination Completed.
