The choice of resin
The primary problem with the design of a cable material formulation with good processability and physical and mechanical properties is the selection of suitable PVC resins. The higher the polymerizability (molecular weight) of PVC, the higher the tensile strength, impact strength and elastic modulus of the product, the better...
Volkswagen Norway's Innovation Norway will select 10,000 families that are not in power in Romania to finance their networking.
According to local media reports, bank representatives have begun to start the family selection of documents. The Romanian authorities have sent a list of 21,000 families without electricity. However, Romania has...
Due to lack of electricity in a few days to reach 5,000 megawatts, Pakistan's power to rise to maximize.
2 days after the increase of 1500 MW of electricity, the supply and demand gap is still 5,000 MW.
At present, Pakistan's total power generation reduced to 9400 megawatts, while electricity demand remained at 14,700 megawatts. And hydro...
Qatar Telecom's Southeast Asia - Middle East - Western Europe 5 submarine cable system (SEA-ME-WE5) will be put into operation this year.
20000 km of cable is developed as a multi-zone data highway to improve data transmission in affected areas and provide network traffic flexibility to Oman.
Southeast Asia - Middle East - Western Europe 5 su...
(1) sound measurement method: the so-called sound measurement method is based on the fault cable discharge sound to find, the method for high-voltage cable core wire on the insulation flashover is more effective. The equipment used in this method is a DC voltage tester. In the fault at the cable core wire on the insulation discharge "Zizi, Zi" spark disch...
1, cable carrying capacity
Aluminum alloy resistivity between aluminum and copper, slightly higher than aluminum, and lower than copper, in the same cut-off capacity under the premise of the same length of aluminum alloy conductor only half the weight of copper. Thus, when the alloy conductor has a cross-sectional area of ??1.5 times that of copp...
Aluminum alloy cable originated in the North American market, was used in airports, military bases, office buildings, residential, hotels, supermarkets, institutions, stadiums, hospitals, factories and other construction projects, more than 40 years has never been any security incidents.
In terms of electrical performance, aluminum alloy...
The EU Executive Committee said it had approved a Czech subsidy program worth 420 million euros for more efficient power plant power generation.
The European Commission said that the plan will help the Czech Republic to achieve 2020 renewable energy, energy efficiency and greenhouse gas emissions targets, while not affecting its competitiveness...
After the operation, the same cable between the different core, close to the laying of parallel cables between the existence of electrical interference problems, the main cause of electrical interference are:
In order to ensure that the control cable in the event of insulation breakdown, mechanical damage or fire, reduce the scope of the spread, th...
(1) fire performance
As the mineral cables are all made of inorganic materials, it will not cause fire, can not burn or combustion, but will not produce toxic gases, even if there is burning in the flame, the cable can still work properly. After the fire cleared, the cable without replacement, is a true sense of the fire cable, for the fire line to provide a...
