Known for electric wire and cable industry in the national economy "container" and "nervous". Its main product aerial bundled cable is used to transmit electric (magnetic), information, and realize energy conversion electromagnetic wire products, widely used in all sectors of the national economy, providing important support to industry, nation...
CRU is a global authority on the supply chain of fiber-optic and communications cables and has successfully hosted the world conference on fibre optic cables.
Low-smoke halogen-free cables refer to environment-friendly cables.This shows that good quality LSZH cables can ensure good power transmission quality.
According to the voltage loss or safe carrying, capacity selection can withstand 600 or so. According to the economic current density can be chosen to withstand about 400. The selection of the conductor principle: 1) close by heating conditions of conductor section (safety)2) distance based on safe carrying capacity on the conductor section selecti...
CDWP central development working group of Pakistan today approved 13 such high-voltage transmission development projects, with a total investment of about 91 billion rupees (about 5.5 billion yuan).
Among them, 6 projects have been approved, with a total investment of about 3 billion rupees about 180 million yuan), and the remaining 7 projects hav...
Carry out visits to check on overhead cable, it is one of the basic contents of the overhead cable for operation and maintenance. Through visits to check can detect defects to take preventive measures to ensure the safe operation of the line. Typically, transmission line patrol overhead line work should be done "Nine investigations."
A check...
When a large number of cables are laid in groups, their current-carrying capacity can be reduced due to their mutual heating. Sometimes, cables of big sizes are considered to be replaced by two or smaller parallel ones because the current-carrying capacity in each unit of a section shall be reduced owing to the skin effect and proximity effect of big section...
Ecuador and Chile have resumed negotiation to jointly develop a major copper mine after a years-long stalemate.At the same time,the demand for base metals will surge in the emerging clean energy transition.Chile's national copper producer Codelco agreed to a request by Ecuador's Enami to suspend two arbitration proceedings over the Llurimag...
