Why use Mastar's Copper Aluminum Bimetallic Gaskets?
Avoid electrochemical corrosion
When copper and aluminum are in direct contact, electrochemical corrosion will occur due to potential differences, leading to rapid oxidation and loss of aluminum. Copper-aluminum composite gaskets use intermediate transition materials to isolate the two metals, significantly reducing the risk of corrosion.
Reduce contact resistance
The direct connection of copper and aluminum is prone to produce an oxide layer due to corrosion, which increases the contact resistance and leads to increased power loss. The use of copper-aluminum composite gaskets can ensure stable conductive performance, reduce contact resistance, and improve circuit reliability.
Avoid local heating
Increased contact resistance will cause local heating of the circuit, which may lead to fire or other electrical accidents. Copper-aluminum composite gaskets effectively avoid local heating problems by optimizing electrical conductivity and reducing heat loss.
Improve mechanical connection strength
Copper-aluminum composite gaskets are produced using advanced technology. The two metals have high bonding strength and can provide good mechanical properties to ensure long-term stability of the connection.
Extend equipment life
By avoiding electrochemical corrosion and local heating problems, the service life of electrical equipment is extended, maintenance and replacement costs are reduced, and economic benefits are improved.
Suitable for various industrial scenarios
Copper-aluminum composite gaskets are suitable for various scenarios that require copper-aluminum transition connections in the power, electronics and machinery industries, and can widely meet practical application needs.
Application of Mastar's copper-aluminum composite gaskets
Transformer connection parts
The conductive parts of the transformer usually involve transition connections between copper and aluminum materials. Copper-aluminum composite gaskets can be used at the wiring terminals of the transformer to reduce contact resistance, ensure efficient current transmission, and avoid electrical failures caused by corrosion.
Switchgear and busbar connection
In switchgear and distribution cabinets, copper and aluminum busbars often need to be connected. As a high-quality transition material, copper-aluminum composite gaskets not only improve the mechanical strength of the connection, but also effectively reduce the incidence of electrical accidents and extend the service life of the equipment.
Power equipment installation and maintenance
In the installation and maintenance of power equipment, copper-aluminum composite gaskets are widely used in cable terminals, junction boxes and grounding systems to ensure safe connections between different materials, while simplifying the maintenance process and reducing maintenance costs.
Photovoltaic power stations and wind farms
In photovoltaic power stations and wind farms, there is a high demand for the connection of copper and aluminum terminals. Copper-aluminum composite gaskets can effectively solve the problem of decreased conductivity caused by electrochemical corrosion in harsh environments, and ensure the stability and efficiency of new energy power generation systems.
Electric vehicle charging station equipment
In electric vehicle charging stations, charging modules and their electrical equipment often require copper-aluminum conductor transition connections. Copper-aluminum composite gaskets can provide stable electrical connections, reduce energy loss, and extend the service life of equipment, especially for high-power fast charging equipment.
Smart grid components
In smart grid systems, copper-aluminum composite gaskets are used to connect various interconnected components, such as smart circuit breakers, power metering devices, and distributed power devices, to ensure compatibility and safety between multi-material equipment.
Energy storage system conductor connection
Energy storage systems are widely used in power regulation and backup power scenarios. Copper-aluminum composite gaskets play a key role in their conductive connections, avoiding efficiency losses between battery modules and external conductors due to material incompatibility.
