DESCRIPTION
Hellermann Tyton 70mm² Copper Link: Precision Crimp Connector for 00 B&S/AWG Cables
Engineered for High-Current DC and Automotive Power Systems
The Hellermann Tyton 70mm² Copper Link is a high-performance compression crimp connector designed to join 00 B&S/AWG (70mm²) cables with exceptional conductivity and mechanical strength. Manufactured from 99.9% pure copper and finished with a tin electroplating layer (5–10 microns), this link ensures low-resistance, corrosion-resistant connections in demanding environments. Whether you're building a 12V, 24V, or 48V DC power system, this connector supports reliable energy transfer for automotive, marine, solar, and off-grid applications.
Unlike generic connectors, the Hellermann Tyton CS70-CU-SR is annealed for ductility, reducing the risk of cracking under vibration or thermal cycling. Its bellmouth entry guides stranded conductors smoothly into the barrel, minimising strand damage during insertion and crimping. This attention to detail makes it a preferred choice for professional installers who demand consistent, long-term performance.
Why Choose a High-Purity Copper Link?
In high-current DC circuits, every milliohm of resistance matters. Inferior connectors made from brass or low-grade copper alloys can introduce hotspots, voltage drop, and premature failure. The Hellermann Tyton 70mm² link addresses these risks with:
- 99.9% IACS conductivity – virtually identical to pure copper, ensuring minimal power loss
- Low oxygen content (≤30 ppm) – prevents internal oxidation that degrades conductivity over time
- 40% ductility rating – allows the crimp to deform uniformly around the conductor without fracturing
- Tin plating – protects against corrosion in humid, salty, or acidic environments, common in marine and coastal installations
These properties make the link ideal for 00 AWG battery cables, inverter connections, winch wiring, and solar array combiner boxes where reliability is non-negotiable.
Designed for Professional Crimping
The CS70-CU-SR features a seamless copper barrel with an inside diameter of 11.3 mm and outside diameter of 14.6 mm, optimised for standard 70mm² fine-stranded cable (19 x 2.14 mm strands). The 50.8 mm length provides ample surface area for a secure, low-resistance crimp when using a suitable hexagonal or indent crimping tool. A 3.3 mm wall thickness balances strength with formability, ensuring the link withstands mechanical stress without adding unnecessary bulk.
For installers, the bellmouth profile is a critical feature. It eliminates sharp edges that can cut individual strands, a common failure point in high-vibration environments like engine bays or trailer chassis. Combined with the annealed copper, this design promotes a gas-tight crimp that resists moisture ingress and maintains conductivity over decades of service.

Applications Across Automotive, Marine, and Renewable Energy
This copper link is a versatile solution for any system requiring a permanent, low-resistance joint between two 00 AWG conductors. Typical use cases include:
- Dual battery systems in 4WDs, caravans, and camper trailers
- Marine electrical panels where salt spray demands tinned copper
- Solar PV installations – join cables in combiner boxes or array wiring
- Inverter and charger connections in off-grid power setups
- Industrial equipment and heavy machinery with high-vibration environments
Note: The link is rated for a maximum continuous operating temperature of 155°C, but typical de-rating factors apply based on installation conditions, ambient temperature, and cable insulation ratings. Always refer to local wiring standards when sizing conductors and connectors.
Built to Australian Standards
Hellermann Tyton manufactures this link to AS/NZS4325 Part 1, ensuring it meets stringent requirements for dimensions, material purity, and plating thickness. This compliance gives installers confidence that the connector will perform as expected in critical circuits, from emergency vehicle systems to remote renewable energy sites.

Installer Responsibilities and System Design
HellermannTyton products supplied by us are generally intended to be installed, crimped, terminated, insulated, protected, or incorporated into a broader electrical installation, vehicle, vessel, building, machine, switchboard, cable assembly, or other operating environment. We do not provide installation services unless expressly stated in writing, and we do not supervise or control installation practices carried out by installers, contractors, dealers, resellers, or end-users.
Once installed, the product may form only one component of a larger electrical or mechanical system. The installer, electrician, system designer, integrator, dealer, or end-user is responsible for ensuring that the selected product is suitable for the intended application and is installed correctly.
All HellermannTyton products must be installed and used in accordance with the product documentation, applicable Australian Standards, relevant electrical and industry standards, manufacturer specifications, and recognised industry best practice. The installer must ensure that the product is used within its specified ratings, including cable size, conductor type, voltage, current, temperature, insulation requirements, environmental exposure, mechanical loading and any applicable crimping or shrinking requirements.
Issues or damage arising from incorrect installation, incorrect product selection, poor system design, unsuitable tools, incorrect crimping, incompatible conductors, inadequate protection, inappropriate heat application, unsuitable mounting, or failure to follow instructions are not product defects and are not covered by this warranty.
Warranty Exclusions
This warranty covers manufacturing defects or failures of the HellermannTyton product supplied by us arising from normal use in accordance with the applicable product specifications. It does not cover any failure, damage, performance issue, deterioration, or loss caused wholly or partly by external factors, misuse, incorrect installation, or circumstances outside our control.
Warranty exclusions include, but are not limited to:
- Incorrect installation or handling: Damage or malfunction caused by incorrect crimping, incorrect die selection, incorrect tool use, incorrect heat application, incorrect sizing, poor conductor preparation, incorrect stripping, incorrect torque, incorrect mounting, mishandling, or failure to follow applicable instructions or standards.

Making a Warranty Claim
Important: If you suspect a fault with a HellermannTyton product supplied by us, do not remove or alter the product unless it is unsafe to leave it in place or unless authorised by us or the place of purchase. Premature removal, cutting, re-crimping, reheating, or alteration may prevent proper assessment and may limit warranty coverage.
- Contact the place of purchase: Warranty claims should be initiated through the authorised dealer, reseller, distributor, or place of purchase.
- Provide product information: The customer must provide proof of purchase, product model or part number, batch or identification details if available, a description of the issue, and photos or videos showing the product and installation.
- Provide installation details: We may request information such as cable size, conductor type, tool and die used, crimping method, heat source used, installation environment, connected equipment, load conditions, and applicable test results.
- Assessment and troubleshooting: The product and installation details may be assessed to determine whether the issue is likely to be a product defect or caused by installation, product selection, connected equipment, environment, misuse, or another excluded factor.
- Return for inspection: If the fault cannot be confirmed by correspondence, photos, or remote assessment, the product may need to be returned for inspection, testing, repair, or replacement assessment. Return instructions will be provided by the place of purchase or nominated assessment location.
- Evaluation and outcome: If the product is confirmed to have a defect covered by this warranty, an appropriate remedy will be provided. If the product is found not to be faulty, or the issue is caused by an excluded factor, the claim may be rejected.
