Global Renewable Usage Trajectory

Solar Energy

Projections show that solar energy generation will account for approximately 35% of total energy generation by 2050.
Wind Energy

By 2050, both offshore and onshore wind energy generation will account for approximately 30% of total energy generation.
Battery Energy Storage

Scaling up battery energy storage is crucial to improve the alignment of solar and wind energy outputs with electricity demand patterns and system needs, providing hour-to-hour flexibility and grid stability.

Electrical Installation Challenges

Downtime due to faulty connection

After a cable accessory is installed, it could be subject to non-standard service conditions and/or adverse environments. This can affect the long-term performance and life expectancy of the splice causing a failure.

Solution:
3M™ Cold Shrink QS-III Splice technology is designed for long-term reliability, performance and minimization of potential installation errors.
Trend towards using higher product DC voltage

HVDC technology offers the most efficient means of transmitting large amount of power over long distances, help connect renewables energy to the grid, and stabilize three-phase-grids. That is why it has become a growing trend.

Solution:
The 3M™ Cold Shrink QS-III Splice bodies with its thick, molded outer semi-conductive shell, comply with the requirements of the IEEE 592 offering a superior and more reliable product.
Thermal Runaway Failures

In the renewable energy environment, cable accessories must withstand extreme load cycles and, if not robust enough, will be at high risk of failure.

Solution:
3M™ Cold Shrink cable accessories firmly shrinks onto the cable insulation, providing an active seal, without loss of pressure due to cable heat cycling.
Reducing Neutral Current on Long 35 kV runs

Long runs to the transmission substation can cause high neutral currents which can cause the circuit to be derated.

Solution:
Cross-bond the circuit to reduce neutral current using a well-designed splice combined with high-quality manufacturing. Given the 3M™ Cold Shrink QS-III Splice’s precise geometry, the electrical stresses within the splice are less than those experienced by the cable insulation.
