Development tools play an important role in the history of human progress. China long before 28 BC to 20 century, had appeared brass and copper cone cone, drilling, copper knives and other cutting tools. Late Warring States period (third century BC) Jiaonan manufacturer of industrial casters, mastered the carburizing technology, made of copper knives. Then drill and saw, with a modern flat drills and saws have some similarities. Tool However, the rapid development of the tool is in the late 18th century, with the development of the steam engine and other machines from the. 1783, in the French Le first made the cutter. In 1792, the British system of taps and dies Maudslay. The earliest documented about the twist of invention in 1822, but until 1864 only as a commodity production.

According to the specific characteristics of fire-resistant cable distribution Jiaonan industrial casters, designers design selection should note the following questions: (1) When the fire-resistant cable for cable-intensive cable tunnel, cable sandwich, or near the pipeline, oil depots and other easily Burning place, should first use a Class A fire-resistant cables. Except as described above and the cable configuration is small quantity, can be a Class B fire-resistant cables. (2) fire-resistant cables are mostly used for emergency power supply circuit Jiaonan industrial casters, work normally requires fire. Due to the sharp rise in the ambient temperature fire, in order to ensure transmission capacity of the line to reduce the pressure drop, the supply line is long and strictly limited allowable voltage drop circuit, fire-resistant cable section should be at least one file to enlarge. (3) can not be used as heat resistant cables cables. (4) In order to reduce the probability of failure in the cable connector in the fire, the installation should minimize the number of joints, to ensure that the line can work in the fire. If you need to do branch wiring, respond to the joint fire prevention treatment.
