High voltage cable | fhlr2gcb2g | 35mm²

Voldt® high-voltage cables are designed for applications that require safe and stable transmission of 600 V AC or 1000 V DC power in electric vehicles and related automotive systems. They are suitable for battery packs, inverters, power electronics and high-voltage distribution where insulation integrity and electromagnetic shielding are essential. The cables are built with high tear-resistant silicone insulation and multi-layer shielding for consistent performance in demanding environments.

Beyond basic power delivery, Voldt® high-voltage cables support installations where vibration, thermal stress and electromagnetic interference can influence reliability. The robust conductor design, combined with precise dimensional tolerances, ensures optimal fit and predictable handling during assembly. This makes the cables suitable for both OEM use and professional retrofitting projects requiring verified electrical properties.

Each cable withstands high AC test voltages, maintains stable capacitance and impedance values and performs reliably across wide temperature ranges. These characteristics make Voldt® high-voltage cables a dependable choice for long-term use in electric mobility applications where safety and performance cannot be compromised.

Voldt® high-voltage cables are constructed using a stranded Cu ETP1 copper conductor, surrounded by high tear-resistant silicone insulation and a dual shielding system consisting of a tinned copper braid and aluminium-coated foil. This multi-layer approach ensures effective EMI protection, thermal stability and mechanical resilience. The orange silicone jacket, similar to RAL 2003, provides an additional layer of durability suitable for automotive environments.

The cross-sectional structure is engineered to maintain precise tolerances for diameter, insulation thickness and shielding coverage. These tolerances support safe routing through vehicle compartments and ensure consistent electrical behaviour. The braided shield typically achieves high optical coverage, while the aluminium foil completes the 360-degree shielding envelope.

This construction method aligns with standards such as ISO 6722, ISO 14572 and LV 216-2, supporting installation in systems that require certified materials and predictable performance. All Voldt® high-voltage cables follow the same design philosophy, although specific dimensions and conductor sizes may vary per model.

Voldt® high-voltage cables deliver stable electrical performance, with characteristics such as controlled capacitance, predictable impedance and low conductor resistance relative to the cross-section. They are designed to operate safely at 600 V AC or 1000 V DC and withstand significantly higher test voltages during quality control. This ensures high integrity of the insulation and shielding during long-term operation.

The cables are engineered for a wide thermal range, typically from –40°C to +180°C depending on the silicone formulation. This allows consistent performance in environments where components may face extreme temperature fluctuations across driving cycles. Mechanical properties, such as bending radius and jacket durability, support professional routing through confined spaces.

All models within the category share the same reliability principles: stable electrical parameters, high insulation resistance, effective EMI suppression and construction tailored for automotive applications. These qualities ensure dependable long-term operation in high-voltage systems used in electric mobility.

The main advantage of choosing Voldt® high-voltage cables is the combination of European engineering, high-quality materials and strict manufacturing standards. Each cable benefits from multilayer shielding, high-grade silicone insulation and robust copper conductors that support long-lasting electrical stability. This ensures dependable operation in high-voltage environments subject to vibration, heat and electromagnetic interference.
