Under the HVCRC® brand, Epsilon Composite Cable has developed a complete range of High Temperature Low Sag conductors made of a carbon-glass epoxy composite core and trapezoidal aluminum strands, designed to improve line ampacity, reduce sag and electrical losses.
Compared with traditional ACSR conductors, HVCRC® conductors allow to increase the ampacity of a transmission or distribution line by 100%, or to decrease line losses by up to 30%, among other benefits.
HVCRC® conductors use trapezoïdal strands made of highly conductive 1350-O annealed aluminum alloy. In some cases, Aluminum Zirconium alloy can also be used if required.


HVCRC® Composite cores are made in pultrusion using Aerospace grade Carbon Fibers, with an integrated microcore and protective glass fibers outer layer.
They are qualified according to ASTM B987.
If required, monitoring can be integrated in the composite core to check its integrity during and after installation

HVCRC® conductors are installed using conventional compression tools and accessories, which reduces installation costs & complexity as compared with proprietary accessories used for other HTLS conductors.
As a result, training of installation crews is made easier, and there are less risks of line failure due to improper installation.

For utilities who require the ability to monitor the composite core used in our conductors, we have developed and patented CoreCheck®, a technology relying on breakdown voltage to guarantee the integrity of the composite core at any stage of a project, and which is simple and fast to deploy on the field.
