Circuit breakers can be used as an alternative to fuses, but have significantly different characteristics. This is a cylindrical fuse. When the circuit fails or is abnormal, the current continues to rise, and the increased current may damage some important components in the circuit, or may burn the circuit or even cause a fire. If the fuse is correctly placed in the circuit, the fuse will cut off the current by itself when the current abnormally rises to a certain height and heat, thus protecting the safe operation of the circuit. http://www.wzcfdq.com/cylindrical-fuses/cylindrical-fuse/

The multi-functional mechanical vibration analyzer is a basic instrument for the factory to carry out condition monitoring and realize predictive maintenance. It is a powerful tool for equipment reliability management and TPM. Its simple operation is suitable for equipment maintenance and inspection personnel, as well as production operators, for measuring, recording and tracking machine status, detecting abnormalities, and enabling diagnosis and trend monitoring of common machine vibration failures. http://www.kmvibrationanalyzer.com/vibration-analyzer/

A decorative box is a form of packaging that is generally more than just functional, but also intended to be decorative and artistic. Many such boxes are used for promotional packaging, both commercially and privately. Historical objects are usually called caskets if larger than a few inches in more than one dimension, with only smaller ones called boxes. Traditionally gift boxes used for promotional and seasonal gifts are made from sturdy paperboard or corrugated fiberboard. http://www.ipackagingbox.com/paper-box/gift-box/

Small dry-type transformers are often self-cooled by natural convection and radiation heat dissipation. As power ratings increase, transformers are often cooled by forced-air cooling, forced-oil cooling, water-cooling, or combinations of these. Large transformers are filled with transformer oil that both cools and insulates the windings. Transformer oil is a highly refined mineral oil that cools the windings and insulation by circulating within the transformer tank. http://www.hydgetpower.com/transformer/dry-type-transformer/

Vacuum dryer is the equipment with the help of which vacuum drying is carried out. In the pharmaceutical industry vacuum dryer is known by a common name called vacuum oven. Vacuum dryers are sometimes made up of cast iron, but most now are made of stainless steel , so that they can bear the high vacuum pressure without any kind of deformation. The oven is divided into hollow trays which increases the surface area for heat conduction. http://www.gj-dryingequipment.com/vacuum-dryer/

The global computer bag giant HTTP company launched the world's first backpack in the 1980s. Due to the use of shock-proof protective materials, plus special ergonomic design and unique reinforcement, it is extremely durable and very popular. In addition to the shock-proof protective compartment specially used for holding the computer, the computer backpack also has a considerable space for small items such as luggage. Many high-quality computer backpacks are also widely used as sports travel bags. http://www.galaxytrendbags.com/backpack/computer-backpack/

Stainless steel tube is a kind of hollow long round steel, which is mainly used in industrial transportation pipelines and mechanical structural components such as petroleum, chemical industry, medical treatment, food, light industry, mechanical instrument and so on. In addition, when the bending and torsional strength are the same, the weight is lighter, so it is also widely used in the manufacture of mechanical parts and engineering structures. http://www.chennamachinery.com/stainless-steel-tube/
