Construction and Details of EV Shielded High Voltage Aluminum Core Cable
◆ Aluminum Alloy Wire Cores
Aluminum is a relatively cheap material. It is also lighter in weight than copper.
The core material of aluminum core cable is not pure aluminum, but a special alloy of aluminum that can withstand high voltage. The good performance of the cable lies in cost reduction, weight reduction, and excellent flexibility. This can be helpful in the efforts of EV manufacturers looking to reduce the weight of HV wiring harness
. The lower weight also makes the cable easier to install.
Cross-linked polyethylene (XLPE)/Cross-linked polyolefin (XLPO) is with excellent heat resistance.
The main function of XLPO/XLPE insulation layer is to reduce the power loss caused by high-frequency electrostatic induction and provide a good electrical insulation performance. It also has the functions of reducing the dielectric strength and preventing leakage currents.
◆ Coated with Two Shielding Layers
The aluminum conductor is coated with two layers of protective film: tinned copper braided shielding layers, and aluminum foil shield tape. The braided shield provides electrostatic shielding and blocks electromagnetic interference (EMI). It has high mechanical strength, good flexibility, excellent heat resistance and cold bending performance. The aluminum foil taping can also shield the electromagnetic wave generated by high voltage operation of electric vehicles.
◆ XLPE/XLPO Sheath
The outer jacket is typically XLPE (Cross-Linked Polyethylene), which provides excellent chemical resistance, abrasion resistance and weathering characteristics while providing good mechanical protection against physical damage such as crushing or kinking. The jacket may be either smooth or corrugated depending on the application requirement.
The overall cable construction is designed to provide superior mechanical properties while providing flexibility and ease of handling during installation.
