Shandong winter 103 thousand and 400 users benefit from coal to electricity"

In November 12th, with the completion of the 10 thousand volt Hou camping line of Liaocheng power supply company in Shandong, it marked the successful completion of the construction target of the coal modification power grid project in Shandong in 2017. Shandong electric power has invested 10 thousand volts and below coal to power matching power grid construction funds, 310 million yuan, new construction, transformation of 10 thousand volts line 426.4 km, low voltage line 395.5 km, new distribution capacity of 25.3 million KVA. Speed up the construction of 35 thousand volts and above, increase the power capacity of the power grid, increase the capacity of 242.1 kilovolt AMV, 418.8 kilometers of new and reconstructed lines, and total investment of 1 billion 670 million yuan.According to statistics, a total of 103 thousand and 400 urban and rural users in Shandong will benefit from the heating area of about 9000000 square meters. According to preliminary estimates, after the transformati...

Classification and performance of insulating materials

Planning Association Yao Qiang No. 19, the introduction of general contract in domestic and foreign developmeThere are many kinds of insulating materials, which can be divided into three categories: gas, liquid and solid. The common gas insulation materials are air, nitrogen, six sulfur fluoride insulating PC film and so on. Liquid insulating materials are mainly mineral insulating oil, synthetic insulating oil (silicone oil, twelve alkylbenzene, polyisobutylene, Yi Bingji biphenyl, two aryl ethane, etc.) two kinds. Solid insulating materials can be divided into two types, organic and inorganic. Materials include insulation paint, plastic insulation, insulation paper, fiber insulation products, plastics, rubber, paint and linoleum pipe insulation impregnating fiber products, electrical products and composite film, adhesive tape, electrical insulating organic solid laminate. The inorganic solid insulation materials are mainly mica, glass, ceramics and their products. In contrast, the va...

Influence the properties of insulating materials

development of the construction industry views" (hereinafter referred to as No. 19), third of which clearly put forward to accelerate the implementation of the development of EPC in perfect engineering construction organization mode.As a general contracting the development of electric power industry experience, advocate, recently, deputy general manager, Chinese Power Construction Group China Electricity 1. The insulation resistance and resistivity resistance are the reciprocal of the conductance, and the resistivity is the resistance within the unit volume. The smaller the conductive material is, the greater the resistance, the reciprocal relation between the two. For the insulating material, it is always hoped that the resistivity is as high as possible. 2. The use of the relative dielectric constant and dielectric loss angle tangent insulation material is two: the mutual insulation of the components of the electric network and the medium of the capacitor (energy stora...

Production and manufacture of high quality heat-resistant casing fireproof casing

Brief introduction(Heat-resistant Casing), the heat resisting sleeve alias: fire temperature cable casing, casing. Casing with high heat is loose casing made of glass fiber, and covered with thick iron oxide red silica, can prevent molten iron splash and high-temperature and flame damage, high temperature fire set has three layers of combination of advanced the wear resistance - flame retardant layer, thermal insulation, water resisting fire layer, fireproof layer, use even if the one or two layer is burnt, third layer can be effectively protected, to win time for the next step of maintenance, fireproof products bright color, and has an excellent extension coefficient, hoses, cables and these properties make it suitable for pipeline protection under harsh environment;Performance:Synthesis of special high temperature resistant materials determines the high temperature tube has many other similar materials to replace features: high temperature resistance, thermal insulation performance, ...

Difference between cold shrinkable cable accessories and heat shrinkable cable accessories

The design principle of the XLPE cable head: first of all, the design principle of all cable head should follow the principle of the restoration of the cable body structure of o so that the joint design should conform to China's electrical standards GB 12706-4 and IEC60502-4:1997, and must meet the electrical, physical and chemical properties, to ensure the safety of normal operation operation of electrical equipment and cable head long time. Two, principle and differential cable head design principle should meet and meet the requirements: make the cable in any natural environment can operate safely. To achieve this, four key factors need to be emphasized: sealing, insulation, electric field, process and so on, which are the four important problems to solve the cable head. First, seal 1. Because most of the cable heads are installed in outdoor environment such as overhead and directly buried, waterproofing and moisture proofing become one of the keys to ensure the safe operation of the...
