Product Introduction
Energy Storage System Terminal Wire (also known as ESS cable assembly) is the specialized electrical interconnect used in Battery Energy Storage Systems (BESS).
Definition and Core Function
An ESS Terminal Wire is a prefabricated cable assembly that integrates a high-current, high-voltage connector with a specially insulated cable. It connects individual battery modules to form racks, links racks to busbars, and connects to inverters. Its main goal is to ensure safe, low-resistance power transfer in demanding environments.
Key Technical Specifications
When selecting an ESS terminal wire, look for these critical parameters:
· High Voltage Rating: Typically rated for 1,000V to 1,500V DC to meet utility-scale requirements.
· High Current Capacity: Supports up to 350A (common ratings: 120A, 200A, 250A, 350A).
· Wide Temperature Range: Designed for extreme conditions, often from -40°C to +125°C.
· Fire Safety: Must be Halogen-Free, flame-retardant (e.g., UL94 V-0), and low-smoke (IEC 61034-2).
· Wire Gauge: Supports large cross-sections from 6 AWG up to 4/0 AWG (or metric 25mm² to 50mm²).
· High Current Capacity: Supports up to 350A (common ratings: 120A, 200A, 250A, 350A).
· Wide Temperature Range: Designed for extreme conditions, often from -40°C to +125°C.
· Fire Safety: Must be Halogen-Free, flame-retardant (e.g., UL94 V-0), and low-smoke (IEC 61034-2).
· Wire Gauge: Supports large cross-sections from 6 AWG up to 4/0 AWG (or metric 25mm² to 50mm²).
Key Features
· Polarity Coding: Color-coded housings (Orange/Red for positive, Black for negative) and mechanical keys prevent reverse-connection.
· Environmental Protection: Rated IP67 (waterproof/dustproof) when mated, with UV and ozone resistance for outdoor use.
· Flexible Installation: Some connectors feature a 360° rotatable plug for easier cable management in tight battery racks.
· High Durability: Supports 500+ mating cycles with low contact resistance (≤5mΩ).
