T2Y2 Red Copper Contact for Fuse material properties
1.The copper of Fuse Terminal Contact has good electrical conductivity, thermal conductivity, corrosion resistance and processing properties, and Fuse Terminal can be welded and brazed. Contains less impurities that reduce electrical conductivity and thermal conductivity, and trace oxygen has little effect on electrical conductivity, thermal conductivity and processing properties.
2.The copper terminal of EV Automotive Fuse Terminals High purity, conductivity not less than 98%.
3.The Copper of Fuse Terminal Contact is No "hydrogen disease" or very little "hydrogen disease"; good processing performance and welding, corrosion resistance and cold resistance.
4.Fuse Link Contact Copper material has good welding performance and cold bending performance, generally no "hydrogen disease" tendency, can be processed and used in a reducing atmosphere.
5.The addition of a small amount of silver to copper can significantly increase the softening temperature (recrystallization temperature) and creep strength, with little reduction in copper electrical conductivity, thermal conductivity and plasticity. The aging hardening effect of silver copper is not significant, and cold work hardening is generally used to improve the strength. The copper terminal of Fuse End Blade Ferrules has good wear resistance, electrical contact and corrosion resistance.
Material properties of Fuse End Caps Brass material
The performance of H65 Brass Inner Cap is between H68 and H62, the price is cheaper than H68, and it also has higher strength and plasticity, Brass Inner End Cap can well withstand cold and hot pressure processing, and has a tendency to corrosion cracking.Mainly used in the production of EV Fuse Brass Inner Outer Cap,PV Fuse Outer Brass Cap, Nickel Plated Brass End Caps,mainly used as electrical, thermal, corrosion-resistant equipment.
1.Brass of Fuse Inner Cap has very good plasticity and high strength, good machinability, easy welding, and general corrosion stability.
2.Brass of Brass End Cap has high strength and plasticity, can well withstand cold and hot pressure processing, and has a tendency to corrosion cracking.
3.H65 brass of Fuse End Caps has good mechanical properties and wear resistance, and can be used to manufacture precision instruments and Fuse Contact parts.
What are the superior properties of photovoltaic fuses
With the vigorous development of solar panels, photovoltaic fuses with Copper Pressure Tube Cap Fitting also play a vital role. Because professional photovoltaic fuses can isolate photovoltaic current in time when the solar panel is short-circuited. Thereby, the solar panel can not be fully protected by traditional fuses.Let's take a look at the superior performance of photovoltaic fuses which has Copper Cap High Pressure OEM.
1. Comprehensive protection
Because ordinary fuses which Tin Plated Copper End Caps can be activated and blown under a certain current pressure, so as to protect the electrical parts of the equipment from being damaged. However, when the solar panel is short-circuited, the amount of current generated is not particularly large, so it cannot effectively start the ordinary fuse, but the photovoltaic fuse with Copper End Caps Round can effectively break the low-voltage current, so it can fully protect the solar panel.
2. Fast fuse response
Since the conduction speed of the current is very fast, if the solar panel is short-circuited, it will lose the meaning of protection if it cannot be blown in time. Therefore, in order to avoid this kind of thing, the photovoltaic fuse with Fuse Contact Copper adopts advanced manufacturing technology and selects stable and reliable raw materials, so that the fuse of Terminal Contact response is rapid, and the fuse can be started at the moment of a short circuit, so as to prevent the electrical components from being burned.
3. Wide range of use
Photovoltaic fuses which have Copper End Caps in the industry are produced in accordance with international standard specifications, so they can be applied to various current ranges, and are equipped with standard metal ferrules, bolts and multi-purpose circuit boards, and the installation method can be based on the actual situation. The application situation can be flexibly selected, so the applicability is very strong.
Application of new energy vehicle fuse
EV electric vehicle fuse: The EV fuse with End Cap and Contact used in electric vehicles not only needs the fuse protection performance of DC high-voltage fuses in ordinary power distribution systems, but also needs to withstand the shock and vibration of road vehicles. A unique class of requirements for the Contact Knife Cap Fuse used.At present, the working voltage of passenger cars is generally above 370V, and that of buses is above 576V, which is much higher than the 12V/24V of traditional automotive electrical components. Such a high working platform voltage requires End Cap Terminal EV/HEV fuses to have both the high breaking capacity of low-voltage fuses and the high reliability of automotive fuses with Outer Cap Contact.In addition to the power battery main fuse, there are also automotive air conditioning systems, heating systems, and DC/DC systems (converting the power battery voltage to 14 V to provide the vehicle Low-voltage power supply, similar to generator) and other accessory high-voltage circuits, each circuit needs to be connected in series with a DC high-voltage Copper Cap Contact Fuse for circuit protection.
In the high-voltage distribution box of an electric vehicle, the output terminal is mainly connected to the auxiliary power supply system of the vehicle, and the inside of the distribution box generally includes an electric heating fan branch, an air-conditioning compressor branch, a DC/DC branch and a charger branch. These four branches, each branch needs to install line protection Knife Contact Fuse, the purpose is to cut off the power protection circuit in time when each load is short-circuited, and avoid vehicle fire. With the comprehensive advantages of small size, good shock resistance and low price, fuses have been widely recognized and used in large quantities, and have become the main components Fuse Terminal recognized at home and abroad as the short-circuit protection of electric vehicles.
For the Copper Contact Cap fuse standard system, it is mainly divided into IEC standard, UL standard and ISO standard. Among them, Chinese GB, German DIN and British BS basically adopt IEC standard. IEC standards mainly include IEC 60127, IEC 60269, etc. UL mainly includes UL248, etc. ISO mainly includes ISO 8820 series.
