High-voltage small busbar cable model and specifications

Optical access and telecom site reference Published 15 Feb 2024

Use this reference to prepare product questions for CGWEB NETWORKS. Check interfaces, capacity, protection and installation requirements against the current product documentation.

High voltage small busbar cables are compact, customizable conductors designed for safe, high-current transmission in constrained spaces, commonly used in electric vehicles, rail systems, and power electronics.

Materials and Construction

High voltage busbars are typically made from highly conductive copper (Cu OF or Cu ETP) or aluminum (EN AW 1070A H112), providing excellent electrical performance while maintaining a smaller cross-section for space efficiency. The conductors are insulated with PA12 (Nylon) layers, which offer high voltage insulation up to 30 kV, excellent bendability, and mechanical strength. Laminated busbars may use ETP copper with FR4 or G10 insulation for compact, multi-layer designs suitable for high-current applications.

Design and Customization

Busbars are available in various sizes and shapes, with flexible areas to compensate for tolerances and prevent vibration damage. They can be fully customized in terms of length, shape, and integration with flexible busbars or high-voltage connectors.

T

E Connectivity and Intercable provide custom solutions for electric vehicles and rail systems, including insulated tubing (BBIT) and support insulators for robust, low-profile installations.

Applications

High voltage busbars are used in: Electric vehicles (EVs) for battery interconnections and power distribution. Rail systems for connecting pantographs, circuit breakers, and inter-car rooflines. Power electronics including DC links, IGBT modules, and high-current inductors.

Renewable energy systems like solar and wind power. Aerospace and military applications requiring compact, high-current interconnections.

Key Features

High current carrying capacity with low resistance. Compact and lightweight design for space-constrained environments. Enhanced safety with high-voltage insulation and protection against short circuits.

Easy installation with pre-fixed screws, plastic caps, and corrosion-resistant coatings. Customizable for specific operating conditions, including multi-layer laminated designs and conductor plating options.

Models and Variants

Extruded busbars: Single-layer, flexible, and suitable for EVs and compact installations. Laminated busbars: Multi-layer, compact, and ideal for high-current electronics and aerospace applications. Inter-car jumper cables: Low-profile, maintenance-free solutions for rail vehicles.

Custom E

V busbars: Optimized for specific vehicle designs with advanced simulation and manufacturing processes. High voltage small busbar cables combine high conductivity, compact design, and customizable insulation, making them essential for modern high-voltage systems across automotive, rail, and industrial applications.
