GBP Inc. (Headquarters: Tokyo), a developer of comprehensive solutions for renewable energy, is launching a new product that allows for the direct connection of copper and aluminum cables outside of control panels, without the need for terminal blocks. It supports 14sq to 500sq and installation is completed without crimping or compression tools. It has been verified through performance tests based on JIS C 2810 for low-voltage applications.
## Background: Traditional Challenges in Copper-Aluminum Straight Connection
Directly connecting copper and aluminum causes galvanic corrosion (electrolysis). Therefore, conventionally, a method using copper-aluminum composite (bimetal) terminal blocks has been used for connection. However, this method requires space for terminal block installation, which constricts the inside of the panel, and increases installation labor for mounting terminal blocks and making bypass wiring.
## Product Overview
GBP's newly launched mechanical connector for straight connection of copper and aluminum cables features a structure designed to suppress corrosion, enabling direct connection of copper and aluminum cables without a terminal block. Its features include simultaneous realization of space saving, reduced installation labor, and uniform installation quality.
## 3 Features
**1. Wide Conductor Size and Voltage Range Support**
It covers conductor sizes (14sq to 500sq) compliant with Japanese cable standards and can support applications from low-voltage wiring to high-voltage applications of the 35kV class. For low-voltage applications, it has been verified through performance tests (tensile strength, temperature rise, electrical resistance, connection stability) based on JIS C 2810.
**2. Installation Without Crimping or Compression Tools**
Crimping or compression tools are not required; installation is completed by simply tightening with a general electric screwdriver or wrench. The tightening screw employs a structure where the head breaks off when the specified torque is reached (torque management mechanism), allowing visual confirmation of completion at the correct torque when the screw head shears off. This ensures stable installation quality independent of worker skill, contributing to reduced field work burden and shorter installation times.
**3. Insulation Support**
For low-voltage applications (under 600V), a standard cold shrink tube is included, allowing immediate installation upon arrival for insulation protection, waterproofing, and reinforcement of the connection part. For high-voltage applications (up to 35kV class), it can be used in combination with commercially available straight connection insulation materials. Please select insulation material suitable for the operating voltage and perform insulation treatment according to the recommended methods of each manufacturer.
