High-performance and robust power connectivity solutions for BEV, hybrid, fuel cell, and ICE platforms
Across North America’s commercial vehicle market, operational uptime is essential for every powertrain. For buses, medium- and heavy-duty trucks, as well as construction, agriculture, mining and specialty vehicles, as an automotive cable manufacturer, we provide a broad portfolio of high and low voltage cables, including both shielded and unshielded solutions. Engineered for demanding environments, these solutions are rigorously validated against North American and global automotive standards.

Can you reduce cable size without sacrificing performance?

Conventional corrugated tubes trap heat around high voltage cables, often requiring larger conductors and more copper.
RADOX® high voltage cables dissipate heat more efficiently, eliminating the need for a corrugated tube in many applications. This allows a 70 mm² RADOX® cable to deliver the same current-carrying capability as a 95 mm² cable in a tube, while reducing weight, cost and cable diameter.
Benefits
- Up to 30% lower weight
- Approximately 25% lower cable cost
- Reduced copper consumption
- Smaller cable diameter
- Lower carbon footprint

What is RADOX®?
RADOX® stands for "radiation X-linked" and describes the process of crosslinking thermoplastic polymers by means of electron beams. HUBER+SUHNER has been using this technology, which was developed in-house since the 1970s to achieve notable improvements in the thermal, mechanical and chemical properties of the cable insulation material.

RADOX® cables support gangway applications
Electric articulated buses place extreme mechanical and environmental stress on gangway cables. HUBER+SUHNER’s screened RADOX® 155 / RADOX® Elastomer S cables proved highly durable in a specialised test rig, offering flexibility, strong EMC shielding and UV resistance without extra protection—demonstrating they are well‑suited for dynamic EV gangway applications.

Introducing the RADOX® 185 mm2: a new high voltage FLEX screened cable for intensive EV applications
HUBER+SUHNER has introduced the RADOX® 185 mm² FLEX screened high‑voltage cable for heavy‑duty EV applications such as mining, agriculture and marine. Designed for harsh environments, it offers high abrasion, pressure and chemical resistance, remains flexible from -40 °C to 150 °C, and delivers strong performance at high AC currents. Despite its large cross‑section, it requires up to 30 % less bending force than standard cables—providing durability, flexibility and reliability for intensive electric‑vehicle operations.

Combining RADOX® HV & TE HIVONEX connections for better EV performance
To improve the durability and reliability of the high voltage assembly in electric vehicles, HUBER+SUHNER and TE developed a joint solution combining RADOX® high voltage screened EV cables with TE’s PowerTube connectors, assembled using Electromagnetic Pulse Technology (EMPT). The result delivers robust, vibration‑resistant, 360° EMC‑shielded connections that withstand extreme temperatures and meet stringent safety approvals. With in‑house EMPT capability and configurable pigtail lengths, HUBER+SUHNER can rapidly support prototypes and small‑series builds, helping OEMs accelerate development while ensuring long‑term connection performance.
