3M Scotchlok 314 Prevents Moisture in Stadium Electrical Systems

Prevent Moisture in Electrical Systems

3M Scotchlok 314

The electrical systems used in stadiums are often exposed to harsh weather conditions such as heavy rain and moisture, creating serious consequences if they fail, with events potentially cancelled or delayed. Problems can occur in hard to reach areas such as floodlights or roof lights, making repair and maintenance difficult and expensive.

Moisture can get into places such as the junction boxes that connect to lighting and other electrical systems, creating poor and unsafe connections. These problems can be solved using 3M Scotchlok 314 Insulation Displacement Connectors (IDC’s), which prevent moisture from getting into electrical installations and causing damage.

3M Scotchlok Insulation Displacement Connectors

Proven Cable Splicing Technology Designed for your Specific Applications

Scotchlok 314 is an insulation displacement connector used for assembling electrical installations. The wires are inserted into the Scotchlok connector, and when the installation is complete, the connection is secured. This makes it easy and simple to work with, especially in difficult situations.

Due to the connector’s moisture-repellent properties, it’s extremely good for outdoor electrical installations such as exterior lights, signs, sprinkler systems, landscape lighting and other moisture resistant applications at low voltage.

• A “live-spring” joint is made by driving the “U” contact down into the connector
• As the “U” contact is pressed into the connector, it grasps the conductors as it displaces insulation
• The contact grips the conductor(s) and holds with firm, resilient pressure

Scotchlok IDCs incorporate a full wire range capability, an increased port size that accommodates up to 4.82mm insulation sizes, double “U” elements and a solvent-resistant plastic construction.

There are 15 different 3M Scotchlok IDCs to choose from to meet a variety of uses, including fixture, appliance, automotive, marine and control circuit wiring.

3M Scotchlok IDCs have a range of approvals and ratings that meet with industrial standards. To learn more give us a call.

Are You Ready For An SF₆ Phase Out?

3M Novec Insulating Gas

Sustainable SF₆ alternative

The EU commission DG CLIMA has issued a new report on Sulphur Hexafluoride (SF₆) alternatives and potential SF₆ phase out scenarios related to the so-called F-gas regulation (EU Regulation 517/2014). Usage of SF₆ has been banned already in multiple applications with electrical equipment being excluded from these restrictions up to now.

The EU report is assessing the availability of SF₆ alternatives and giving an evaluation for a potential SF₆ phase out 3M Electrical Novec Insulating Gases are the ideal SF₆ alternative as they combine excellent dielectric performance and safety with exceptional environmental properties. Used as part of a gas mixture, Novec Insulating Gases reduce the greenhouse gas potential of more than 99% in on-grid commercial equipment.

3M partners GE, ABB & Hitachi ABB Power Grids are using Novec Insulating Gases as part of their SF₆ free products in multiple medium- and high-voltage application going back to first installations in 2015.

In total, more than 25 installations are already running or are currently being installed in Europe by multiple leading Transmission and Distribution System Operators (TSO’s and DSO’s) which make Novec Insulating Gases a well proven SF₆ alternative.

EU Stakeholder Workshop Discussing SF₆ Phase Out Scenarios

In a next step the EU Commission (DG CLIMA ) has invited related stakeholder including member states, switchgear OEM’s, utilities and NGO’s to discuss potential SF₆ phase out timings. The workshop is based on the 2020 EU report and additional input the commission has received via direct consultation with related stakeholders. It is expected that the commission will issue a proposal for the revised F-gas regulation by the end of 2021 and the regulation will take effect end of 2022/beginning of 2023. It is therefore time to act and to start implementing suitable SF₆ alternatives!

Replacing SF₆ In Electrical Gas-insulated Switchgear – Impact Analysis for EU 28

In addition, a recent study conducted by the University of Antwerp concluded that the reported SF₆ stock and emissions are significantly underestimated. The study also provides an estimate of CO₂ eq savings for potential SF₆ phase out scenarios using the example of a 145kV Gas Insulated Switchgear (GIS).

Continuous Shearhead Bolt vs. Crimp Compression Technologies By 3M Electrical

3M Electrical

Comparative Study

The power utility industry is risk-averse.

The decision to change a technology is not taken lightly. You need data, you need research, and you need proof that what you’re using is most reliable, so you can have peace of mind when powering entire cities.

Currently in Canada cable crimp compression technology is the more predominate technology for LV MV HV cable connections. However, just because its what’s you’re used to or many companies use it doesn’t mean it’s the most reliable solution of splicing, connecting or terminating cables.

This is why I conducted a cable connection comparison study to compare continuous shearbolt and crimp compression technologies. The goal of this study was to determine which solution offered superior cable connection reliability.

So, utilities could have peace of mind. Here are my study results.

Continuous shear vs. crimp compression.

An easy distinction between continuous shear technologies and crimp compression technologies is that in a continuous shear installation the lug or connector is installed by continuously shearing off the bolts. Where as, with crimp compression technologies you must crimp a connector or lug using a die and special crimping tool.

The study results: how did continuous shearhead bolt technology and crimp compression technology stack up against each other?

My research found that not only does continuous shear technology offer better performance, it also helps enhance the safety and reliability of the network while driving total cost of ownership down in the long run.

This study proved that, despite some benefits, such as offering standardisation improvements, crimp compression technology (CSA hex die system) is not a fool proof solution. A critical shortcoming is that utilities do not have full control in terms of quality or installation because CSA hex die dimensions are proprietary to the die manufacturer.

This can prevent utilities from being able to fully dimensionally check the dies before releasing them for use in the field. This can be problematic because any slight variation in manufacturing tolerances from one crimping tool manufacturer to another, and one die manufacturer to another, as well as small dimensional differences, or variations in material hardness of the connectors and/or lugs, can determine whether it was a successful or failed installation. In short, there’s not enough control, therefore crimp compression technologies like CSA hex die systems are less predictable.

But, with continuous shear technology that shortcoming does not exist.

The winner: continuous shearhead Bolt technology

Our study found various reasons reinforcing continuous shear technology as the more reliable solution. Here are three critical takeaways:

1. Enhanced performance: continuous shear technologies, like 3M Mechanical Shearbolt Lugs and Connectors are equipped with scientific design elements, such as the predefined contact points, incorporated elasticity, mitigation of contact aging, and optimisation of contact force – offering superior cable connector performance compared to existing technologies, like crimp compression technologies.
2. Operates at lower temperatures: In the comparative heat cycling testing, we found that 3M™ Mechanical Shearbolt Lugs and Connectors operate at lower temperatures. This is important because it means that the connector will thermally age less, so it will last longer compared to aluminium crimp compression connectors under the same test conditions.
3. Ease of install: continuous shear technology, like 3M Electrical Mechanical Shearbolt Lugs and Connectors, is easy to install because of its range taking capabilities. It also does not require any additional tools or dies and can accommodate both copper and aluminium conductor types.

Study highlight: The continuous shear technology plays an important role in an aging utility infrastructure that requires substantial upgrades. It also offers new project construction options for a more robust and reliable, electrical network.
