In electrical engineering in the length of the longest chain pendant chain is how much
Among them, the "wire free force" based, length is not required. Hope to be of help to you.
with its soft wire hoisting; light is over 0.5kg by the chain, and the soft electric line encoder fork in the chain, wire do not force.
n the "code for construction and acceptance of" the construction of electrical engineering with a provision: soft core light at 0.5kg and below,
The chain length in electrical engineering is no specific requirements,
