Custom Insulation Ring Terminal 18AWG 16AWG 14AWG Wire Harness Assembly for Battery Photovoltaic Ground Wire
The Custom Ring Terminal Wire Harness is designed for reliable grounding and low-voltage electrical connections in battery systems, photovoltaic (PV) installations, industrial control equipment, and electrical cabinets. Manufactured with high-quality stranded copper conductors and insulated ring terminals, the harness provides stable conductivity, mechanical durability, and easy installation.
Available in 18AWG, 16AWG, and 14AWG, this wire harness can be customized in length, terminal size, insulation color, and marking to meet various OEM and project requirements.

The harness is manufactured using fine-stranded oxygen-free copper conductors to provide low electrical resistance, stable current transmission, and long-term reliability.
Equipped with insulated ring terminals that help reduce the risk of accidental short circuits while providing a secure and reliable connection to grounding points, batteries, and electrical equipment.
Standard wire sizes include:
Other conductor sizes can be manufactured according to customer specifications.
The multi-strand conductor offers excellent flexibility, making installation easier in control panels, battery compartments, junction boxes, and confined spaces.
The wire insulation provides resistance to abrasion, moisture, oil, and general mechanical wear, ensuring stable performance in indoor and outdoor environments.
