Nuclear Power Cables
A broad portfolio of mission-ready power cables for nuclear platforms—from approved safety-related Class 1E designs to screened, high-temperature and fully customized solutions for harsh environments.
Nuclear power distribution is not a single-cable problem. Habia offers approved and application-specific single-core, multicore, screened, armoured, high-temperature and hybrid constructions. These are fully supported by custom designs when standard options cannot meet the strict electrical, mechanical, or safety qualification requirements.
The right solution may be a recognized nuclear type, or a purpose-built combination. Selection begins with safety classification, voltage, current, cumulative radiation dose, and LOCA survival profiles. A power cable should fit the system, operating environment and qualification plan, not force unnecessary size, weight or termination strain into the safety containment structure.
The Unique Strengths of Habiatron Power Cables
Habia brings together a wide nuclear power-cable portfolio rather than a single solution. It includes cable types to recognized nuclear frameworks such as IEEE 383, thin wall, lightweight and low-fire-hazard containment constructions, high-temperature designs and fully customized cables.
This breadth allows the construction to be matched to the real constraint: safety classification (Class 1E and non-Class 1E), electrical load, voltage drop, routing space, thermal exposure, radiation dose, fire performance, EMC, or regulatory approval. Conductor, insulation, screening, armour, sheath and auxiliary elements can be selected together for safety-critical, primary-side, and balance-of-plant programs.

Insulation and Jacket Materials for Nuclear Power Cables
Power-cable materials determine current capability, size, weight, flexibility and survival in the plant environment. Habia matches insulation and sheath systems to voltage, temperature, cumulative radiation dose, fluids, abrasion, fire behaviour and qualification requirements.
-
ETFE
A strong choice for thin-wall, lightweight power cores requiring toughness, flame performance and broad fluid resistance across demanding nuclear specifications.
-
HFI 260
An aromatic thermoplastic polymer with excellent mechanical and chemical resistance properties even at high temperatures, highly radiation tolerant. thin wall, halogen free, low smoke and low flame propagation.
-
HFS 80 N
A flame-retardant low-smoke zero-halogen (LSZH) sheath associated with heavy-duty power routes. Extensively tested for applications requiring maximum fire, pressure, and radiation protection.
-
HFS 105 XL type B
A rugged, radiation-crosslinked, flame-retardant low-smoke zero-halogen (LSZH) sheath associated with heavy-duty power routes. Extensively tested under LOCA conditions for containment applications requiring maximum fire, pressure, and radiation protection.
Certificates and Approvals
Habia manufactures nuclear cable types approved to, or in accordance with, recognized international regulatory and quality frameworks. Depending on the construction, these can include selected parts of [e.g., ASME Section III, IEEE 323, IEEE 383, RCC-E, KTA] as well as plant-specific type approvals and certifications from independent testing bodies or nuclear authorities.
Important: Approvals apply to specific cable types and constructions. Confirm the required standard, manufacturing site and certificate status with Habia before specifying. Please contact us to get more information about the specific approvals.
Applications for Nuclear Power Cables
Primary Containment (Class 1E Harsh Environment)
Reactor coolant pumps, heavy-duty valves, and safety-critical actuators inside the containment require solutions certified for LOCA environments. Cables range from recognized standard types to rugged designs, selected around high current, cumulative radiation dose, and rigorous regulatory qualification.
Emergency Power and Safety Systems (Class 1E Mild Environment)
Diesel generator buildings and safety-related switchgear need fixed and flexible power routes that balance confined installation, low-fire-hazard behaviour, plant fluids and long-term maintenance access. Options include screened or armoured designs.
Fuel Handling and Cranes (Non-Class 1E / Operational)
Refuelling machines, overhead gantry cranes, and underwater handling systems place a premium on power density, temperature performance, tensile strength, and long-term radiation aging. Thin-wall polymers, lightweight custom constructions, and high-voltage solutions provide different routes to the required handling system power architecture.
Your Custom Cable, Right at Your Fingertips
Bring the difficult requirement first.
Habia’s value starts where catalogue power cable adds avoidable copper, weight or termination stress. Share the safety classification (Class 1E or non-Class 1E), voltage, current, duty cycle, voltage-drop limit, routing, movement, temperature, cumulative radiation dose, LOCA profiling, and qualification route; Habia can turn them into a manufacturable, documentable power-cable design.
