Cable connectors, cable sleeves, and cable trays are widely used in electronic communications, energy, and electrical power systems. Parts of these engineering systems must be electrically conductive and fully screened and touchable to provide complete safety for personnel. Graphene nanotubes outperform conventional conductive additives, providing inner and outer semi-conductive layers of cable accessories with stable and consistent resistivity, longer service life due to enhanced strength, and easy processing thanks to the very low dosage required. This unique combination of properties not only ensures reliable cable protection even after aging but also delivers excellent surface quality and extended durability.
Medium voltage cable accessories are essential in power distribution, industrial installations, renewable energy, transportation, and construction—anywhere cables are terminated, joined, or connected, especially in high-voltage and sensitive environments. Semi-conducting layers in cables make the electric field manageable and uniform, eliminate high-voltage danger zones, and thereby significantly increase the reliability and service life of cable insulation.
To provide effective semi-conductive properties, they must meet strict volume resistivity requirements of <50 Ω∙cm.
Ultra-long, flexible, and conductive, graphene nanotubes form a robust 3D network in materials at ultralow concentrations of 0.15–0.3 wt.%. Unlike carbon black, multi-wall carbon nanotubes, and polymer-based anti-static agents—which require high dosages, lose conductivity over time, weaken mechanical properties, and complicate processing—graphene nanotubes enhance durability and ESD protection while preserving elasticity and hardness, outperforming conventional conductive additives across all key parameters.
TUBALL™ allows to better maintain the balance of properties of the LSR
From 0.1 wt.%, TUBALL™ MATRIX in rubber forms a conductive 3D network, enabling a full range of electrical resistivity of 10–10⁸ Ω, not dependent on humidity and stable over a long service life, safeguarding people and sensitive devices from electrostatic charge and damage.
The distributed, uniform network created by TUBALL™ nanotubes within rubber significantly enhances mechanical properties such as tensile strength, elongation, and tear resistance, providing the end product with a longer service life.
TUBALL™ MATRIX 600 series is a line of concentrates with high-quality dispersed TUBALL™ graphene nanotubes designed for elastomers. They provide compatibility with standard processes and equipment. The concentrates can be added during the mixing or compounding stage and don’t affect the manufacturing process.
