Tungsten Alloy Blank rods are cylindrical bars made from tungsten alloys. These rods are used in a variety of applications such as aerospace, defense, medical, and sports equipment. Tungsten alloy blank rods are known for their high strength, durability, and resistance to wear and corrosion. They are also non-toxic and environmentally friendly. Tungsten alloy blank rods can be machined, welded, and formed into different shapes and sizes to meet specific requirements. They are often used as weights, counterbalances, and radiation shielding materials.

1, the output line terminal before the series 10A, 16A air switch as a short circuit protection. According to the special requirements of the user, the 4, 2, 7, and 1 items in the parameters cannot be opened and closed at the same time and interlocked with each other; however, there is no interlocking between the 6 and 3 items and the above four items. Please pay attention to the requirements in use. It is best to have only one set of power output work at a time. Do not mistaken for other air switches and cause multiple outputs at the same time.
The use of high and low voltage switchgear electricity test bench
High and low voltage switchgear power-on test benches are widely used in high and low voltage switchgear manufacturers to conduct various power tests on high and low voltage switchgear manufactured before shipment. It can provide a variety of AC and DC power supply to facilitate the detection of switchgear and improve work efficiency.
