According to reports, 9.52 billion yuan of power grid construction funds will be given priority to areas with greater demand for load and better investment environment. At the same time, the Shenyang Power Supply Company has changed the way the project was established in the past. The governments at all levels, under the premise of conforming to the power grid planning, reported on the construction projects on an as-needed basis, which were reviewed by the company and enhanced the timeliness and practicality of the power grid construction projects. Power grid construction projects are closer to the needs of regional development.
During the “Twelfth Five-Year Plan†period, a 500-kV Shengjing Substation will be newly built in the Dadong District in the center of the city to solve the problem of power supply capacity and reliability in high load density areas, and solve the problem of subsequent 220 kV transformer substations. The construction of a 500 kV Shennan substation in the southern part of Daban will meet the development needs of the Southern Shenyang Deputy City, the Weinan New District, the Hangao High Base, the Airport New City, the Lixiang New City, and the Manrong Economic Development Zone, and the subsequent 220 kV will be resolved. Substation connection problem.
The focus of the “Twelfth Five-Year Plan†of Shenyang regional power grid construction lies in emerging cities. For example, in the chemical industrial zone, metallurgical zone, economic and technological development zone, and Airport New City of the Western Industrial Corridor, 220 kV of high-calorie, metallurgical, and metallurgical projects are planned and constructed respectively. New legislation and airport changes. Planning and construction of the 220 kV Binhe substation in the core area will address the need for load development in the Golden Corridor area and the Zhongjie area; construct a 220-kilovolt Hanjiang substation to address development needs of the Dadong district mining machinery plant after the relocation In order to meet the demand for development of electricity in the Shenyang Financial and Trade Development Zone, a 220 kV Ningshan Substation was built.
Electric Cable can be divided into building wires and flexible cables
Building wires can also be divided into three types according to the hardness of conductors.
H05V-U/H07V-U voltage class 300/500 or 450/750V. It is the most commonly used connection line for household wiring, mainly used for power supply, lighting, sockets, air conditioners and other daily household lines
H05V-R/H07V-R voltage grade is 450/750V, which can be used for home lighting lines. It is good to use when the wiring is soft and the circuit turns too much, which is convenient for electricians to wear pipes.
H05V-K/H07V-K voltage class 300/500V or 450/750V household decoration is generally not used, and it is suitable for flexible installation sites with strict requirements, such as electrical control cabinets, distribution boxes and various low-voltage electrical equipment.
What is a flexible copper cable?
Copper flexible cables are commonly used to connect portable equipment and appliances. Their flexibility allows them to withstand the movements or vibrations present in a particular application.Flexible copper cables are made from multiple strands of fine copper wire. The conductor is made of normal annealed copper of category 4 and 5. The cable has more than 6 different coloured cores. The insulation and sheath material must have the usual electrical and physical properties. Flexible copper wire is also soft, oil resistant, low temperature resistant and flame retardant.

Applications and features.
Power cables are suitable for use in wet and dry areas, conduits, pipes, slots, trays, antennas supported by messengers, and where excellent electrical performance is required. These cables are capable of continuous operation at conductor temperatures up to 90°C (normal operation in wet and dry locations), 130°C (emergency overload) and 105°C (short circuit conditions). 1/0 AWG and larger are rated for CT use.Household Electrical Wire,Household Application Copper Wire,House Wring Electric Wire,House Building Electric Wires
