Product Overview
The heavy-duty ring terminal for copper conductors from CEMBRE (item number 2389230) is a ring lug designed for connecting copper conductors. The product is specified for low-stranded conductors up to 185 mm² and flexible conductors in the range of 150–185 mm². The ring lug has an M10 screw hole with an eyelet diameter of 10.5 mm and an inner barrel diameter of 19.2 mm.
Material and Electrical Parameters
The tubular body is made of electrolytic copper with a specified purity greater than 99.95%, is annealed, and is electrolytically tin-plated to prevent oxidation. The maximum operating voltage is stated as 35,000 V, and the specified temperature limit ranges from −50 °C to 150 °C.
Installation and Mounting
The installation guide outlines the necessary basic steps for installing the ring terminal:
- Choose the correct lug for the Cu conductor size.
- Strip the cable insulation to a length corresponding to the terminal's barrel length (55 mm).
- Insert the conductor into the barrel.
- Select the correct die size according to the manufacturer's table.
- Apply the correct number of crimps as specified in the manufacturer's table.
Tightening torque is specified at 20 Nm when using high-conductivity screws and 35 Nm when using class 8.8 screws.
The product is intended for use with Cu conductors and has the manufacturer's markings for conductor size and stud dimension on the tongue.
