DigitalBy Ron Tellas

As smart buildings rely on more high-power, long-reach applications, such as PONs (passive optical networks) and BASs (building automation systems), digital electricity cables are becoming a viable option to safely and reliably transmit power and data across long distances.

Relatively new to the market, however, there are a few things you should know about digital electricity cable technology.

1. It supports long transmission distances

With a low mutual capacitance of <50 pF per foot to maintain power-transfer speed, reliable power and data transfer across extended reaches is possible. This makes it ideal for large venues like airport terminals, convention centres, high-rise hotels, hospitals, stadiums and office towers.

2. It supplies safe power transmission

By transmitting “pulses” of DC power, digital electricity cables send energy and data across very long distances in a safe, efficient manner. Data-sensing transmitters and receivers are constantly monitoring line conditions to make sure power pulses are properly received.


If a problem is detected — like an exposed conductor being touched, or a wire being short circuited or incorrectly installed — power distribution stops immediately (within 0.003 seconds) to protect people and equipment. This makes the cable safe to touch, without the worry of dangerous electrical shock.

3. It allows for lower-cost networks

Even when transferring thousands of watts of power, digital electricity networks utilizing digital electricity cables can be installed at much lower costs than traditional networks. They don’t need conduit or armoured cabling, and don’t require an electrician’s time. Instead, a cable installer can used for installation (similar to how a traditional PoE cable would be installed).

4. It establishes better management and control

Digital electricity technology has inherent embedded data capabilities for energy management, monitoring and control. This means it can be used to remotely power and centrally back up systems like DAS remotes, mobile edge servers, PoE LED lighting systems, and IoT sensors.

5. It offers installation versatility and flexibility

With a stranded design, digital electricity cable can maintain flexibility so performance isn’t impacted during installation. It can be used in indoor (plenum and riser), outdoor and overhead/burial applications.

In Belden’s digital electricity cables, digital electricity technology is supplied by VoltServer. The transmitters and receivers are supplied by either VoltServer or JMA Wireless.
Digital electricity cable is available in either copper or hybrid copper/fibre.

Ron Tellas joined Belden in 2016 to help define the roadmap of technology and applications in the enterprise. Prior to this, he developed cables and connectivity for Panduit and Andrew Corp. Ron Tellas is a SME in RF design and Electromagnetic Propagation and has BSEE from Purdue University, a MSEE from IIT, and a MBA from Purdue University.

CSAClimate change and its associated impacts will play a central role in Canada's electricity future. In fact, the Conference Board of Canada estimates that approximately $347.5 billion will need to be invested in electricity infrastructure to maintain the system reliability we have today. Making smart investments now can improve the system and help to avoid more severe climate related costs in the future.

“The critical infrastructure we rely on to power our daily lives must remain resilient to more damaging and frequent extreme weather events,” says Mary Cianchetti, President of Standards at CSA Group. “Standards play a critical role in making that happen.

EHRCIn a recent interview with the The National Post, Electricity Human Resources Canada CEO Michelle Branigan said the need for workers in Canada’s electricity industry is “extremely critical.”

The industry directly employs almost 107,000 people, but less than 1 in 20 is aged 25 or under, only 1 in 4 is a woman, and just over 1 in 10 is from a visbile minority.

These statistics are from EHRC’s Workforce in Motion, a labour market intelligence research initiative for the years 2017-2022. The research report is a planning and informing tool for a wide range of electricity sector stakeholders and provides critical information to the sector for both short and long term resource planning.
