Cable accessories account for the least capital expenditure of a distribution network but can prove to be the weakest component of the system because they have to be assembled on site. This book examines the detailed workings of accessories and provides information to assist engineers and jointers who are responsible for specifying and installing medium voltage cable accessories.
Terminations, separable connectors, cable joints and associated equipment such as cable glands and cleats are examined in detail with explanations of the various technologies used. Great emphasis is placed on failure modes and methods of preventing potential problems in service.
By following the information presented, the reliability of accessories will be improved thus reducing the cost of expensive failures.
This book will appeal to Lead Electrical Engineers, Electrical Project Engineers, Principal Electrical Engineers, Plant Engineers, LV HV EHV Cable Jointers, ATEX Inspectors, Substation Commissioning Managers, LV HV EHV Project Managers, Buyers & Procurement Managers, SAP’s and Sales Managers & Engineers.

Cable Quality is often overlooked when building specification decisions are made, which can result in costly damage and potential loss of life.
BASEC has been in the business of independently testing and certifying cable products and their manufacturing facilities, to internationally recognised standards, for over 45 years.
With a rigorous programme of auditing, inspection and testing their goal is to ensure the cable you specify, source and install is compliant, safe and fit-for-purpose.
The Cable Quality Seminar is designed for anyone and everyone who is working to deliver projects which include cable installations.
Understanding the implications of poor-quality cable and increased awareness of independent cable verification is paramount to your project’s success.
Join us at Tratos to learn how BASEC, recognised instantly in the worldwide cable industry, can help you to be compliant.
Do not miss your opportunity to build your awareness of cable quality.

10 Important Precautions When Working On Low Voltage Energized Equipment (photo credit – pacificsource.net)
With Kind Permission of: Edvard Csanyi (Editor-In-Chief & Electrical Engineer at EEP)
For most work, the electrical equipment must be de-energized because there is a high risk of injury to workers if they work on energized equipment. It may be possible to schedule such work outside of normal work hours to limit the inconvenience.
“Sometimes it is not practicable to completely disconnect low-voltage equipment before working on it.”
For example, it may be necessary to have equipment running in order to test it or fine-tune it. In such cases, the work must be performed by workers who are qualified and authorized to do the work. They must follow written safe work procedures.
You should observe the following important precautions when working on energized equipment, but note that these are not a substitute for proper training and written safe work procedures:
Assess all of the risks associated with the task. Plan the whole job in advance so that you can take every precaution, including arranging for help in case of paralyzing shock. Consider the use of a pre-job safety meeting to discuss the job with all workers before starting the work.
Accurate, up-to-date information should be available to those who work on the system. This means that you should know all equipment installed according to the valid documentation (technical specifications, single line diagrams, wiring diagrams, block schemes etc.).
Be careful, sometimes equipment stated in documentation can differ from the one installed on site – due to the replacing of old (damaged) equipment with the new with similar characteristics.
Have live parts exposed for as little time as necessary. This does not mean that you should work hastily. Be organized so that the job can be done efficiently.
Use insulating barriers or shields to cover live parts. Plexiglas plates can be useful.
Grounded metal parts should be covered with insulating material as much as possible. Very important.

In the video, the door comes off in less than 2 cycles showing that Personal Protective Equipment (PPE) isn’t the only thing to consider when it comes to arc flash. Body position at the point of contact is also important.

Blog Written By BASEC | 6 of 10 Articles
Thorne & Derrick collaborate with BASEC to advocate the importance of electrical safety and educating industry stakeholders about specifying and buying accredited, tested and certified cables and cable accessories.
We would like to thank BASEC for allowing us to republish a selection of articles aimed to protect and inform the electrical sector – together we promote compliance with industry standards, specifications and ultimately confidence in end installations to provide LV MV HV Cable Quality.
In response to direct demands from the marketplace, BASEC has launched a certification scheme to encourage standardised and consistent levels of quality for control cable product ranges, known as YY, SY, CY.
As an authority and preferred testing and certification partner to the worldwide cable industry, BASEC is regularly contacted to support and advise on control cable products comparability and application.
Our new scheme offers the cable industry and its users a way to improve and evidence the levels of quality and safety that the products manufactured, specified or sourced hold. There is presently no referenceable standard in existence, hence the reason these cable products are often a debated hot topic.
The scheme comprises of 6 BASEC specifications BA 1411, BA 1413, BA 1415 for PVC composition and BA 1412, BA 1414, BA 1416 for LSHF composition.
Control cables are found in a vast array of industries, across many industrial and everyday applications. These cable products are flexible, interconnecting and used to measure, control or regulate equipment on assembly or production lines, as well as supporting their associated computer units and work processes.
The new certification scheme is relevant to cable products up to and including 300/500 V, with a maximum conductor operating temperature of 70°C. Standards EN 50525-1 and EN 50565-2, where applicable, will be referenced in conjunction with the control cable scheme document.
BASEC is known within the industry for rigorous certification, factory auditing and testing schemes, which work continuously to improve quality and safety of cable products at manufacturing source. It is with this in mind, that the scheme has been developed, offering an all-inclusive testing programme for this widely used and barely regulated range of cable products. The below summary provides an insight into the depth of the testing which will be undertaken, which will in turn raise the levels of consistent quality in the market.
In 2016, a BASEC original scheme specification BA 1200 developed for single core fire resistant cables, based on market demand, was incorporated as a BS standard.
Now BS 8592 as we know it today.
Our longstanding tenure as a leading testing and certification provider and technical authority leads us to expect this new control cable scheme to hold the same potential – a vehicle to increase standardised levels of quality and safety.
BASEC run a number of FREE Cable Quality Seminar’s across the country suitable for anyone and everyone who is working to deliver projects which include cable installations.
Do not miss your opportunity to build your awareness of cable quality.
