Premium High-Frequency Coaxial Engineering for Next-Gen Broadcasting

The Canare L-CHD and L-CHLT Super Low-Loss Coaxial Cable series represents the highest tier of copper video infrastructure, operating as a specialized 75-ohm transmission line engineered to support uncompressed 12G-SDI, 3G-SDI, and high-definition television distribution networks. In high-end broadcast centers, commercial production hubs, and live event flypacks, moving ultra-high-frequency digital signals over long distances can easily fail when using standard copper wires. Canare’s advanced multi-layer design solves this, delivering clean, bit-accurate data transmission for high-resolution video streams.

Multi-Layer Shielding and Crush-Resistant Dielectric Core

To prevent high-frequency data loss from physical deformation, this series features a unique multi-layer foamed polyethylene insulation system. By applying a different foaming ratio to each layer, the core balances low capacitance ($53\text{ pF/m}$) with the physical strength needed to resist crushing under tension. This specialized layout is backed by a dual-shield design—combining solid aluminum tape with a high-density tinned copper braid—that keeps your digital signals safe from high-power stage dimmers, wireless transmitters, and neighboring equipment lines.

Crucial Installation Note: Canare Super Coax cables are designed primarily for permanent, fixed installations. To prevent structural changes that can degrade your digital signal, please avoid subjecting the cable to repeated bending, sharp crimping, or external rolling pressure. For quick prep work, the L-2.5CHD and L-2.5CHLT models fit perfectly with the Canare TS100 series rotary cable strippers.

Specialized Architectural Variants for Studio Backbones and Weight-Saving OB Vans

To deliver reliable signal tracking across varying physical layout requirements, this premium product family is split into two specialized sub-series:

• L-CHD Heavy-Duty Studio Series (L-2.5CHD to L-8CHD): The baseline standard for master control rooms, central apparatus rooms, and sports arenas. Scales from a slim 4.2mm path up to a massive 11.1mm master backbone line to minimize loop resistance ($5.8\text{ }\Omega\text{/km}$) across large infrastructure footprints.
• L-2.5CHLT Weight-Optimized OB Van Line: A slim 4.2mm profile designed specifically for mobile production trucks and flypack assemblies where space and weight are strictly managed. By swapping the traditional tinned copper shield for a specialized tinned copper-clad aluminum (TCCA) braid, it cuts total cable mass by 30% without sacrificing any transmission distance.
