When the sharp cable tail pierces the wool fabric or the foil gold material contacts the core wire, it may even cause a short circuit. Here, we recommend a useful trick: if you peel off the insulation layer, you can easily push the layer back into the sheath. In the manufacturing process of layers, such layers cannot be applied to the moving high flexible cables in the energy supply system. Of course, Eagles can provide direct solutions to these problems. This sheath ensures that the core of the cable will not loosen when it is moving. The reason is that the sheath is extruded by special pressure. It is like a guide groove, which guides the movement of the core wire and also supports it. So it is very suitable for drag chain. Summarize the mass of high flexible cable applicable to drag chain: center stress relief design; Multi bundle cabling structure; The cable adopts an inner sheath of armor type extrusion molding; Fully insulated woven mesh; Optimized braiding angle;
Fushun high-voltage cable recovery telephone quick door OC door OC door and OD door are defined as follows: OC: Open Collector OD: Open Drain This is named relative to two different components, OC door is relative to triode, and OD door is relative to MOS tube. Let's first analyze the working principle of the OC gate circuit: when the INPUT input is high, Ube0.7V, the triode U3 is on, the potential at point b of U4 is 0, U4 is off, and OUTPUT is high. When the INPUT input is low, Ube0.7V, the triode U3 is off, the potential at point b of U4 is high, U4 is on, and OUTPUT is low. In the OC gate circuit, R25 is the pull-up resistance: what is the pull-up resistance? Pull up the uncertain signal to the high level.
Appearance of DDZ - Ⅱ electric unit combination, power supply is 220V AC， The output signal is 0 -- 10mA DC four wire transmitter has been widely used, and it can be seen in some factories at present. In the 1970s, DDZ - Ⅲ electric unit combination appearance was produced, and the analog signal specification for process control system adopted by IEC was selected. Namely, 4-20mA is selected for external transmission signal DC, 1-5V is selected for contact signal DC， Namely, the signal system of current transmission and voltage acceptance is selected. Select 4-20mA DC signal, two-wire system can be completed on the surface of the site. As an electrical engineer, he should be specialized in one thing and versatile, so as to meet the needs of the company's development. In the future work process, we should strengthen other studies to improve our business and technical level. We should always be strict with ourselves, pay attention to our own development and progress, and be cautious. The foresight and planning in the work process are not strong enough. In the future work, we should improve our foresight for the work that will have problems, try not to have problems, and be able to handle problems in an orderly manner. IV. Next year's work is expected to be a busier year. The business building project will start from March to the capping construction stage, and the Wanli Wood Carving Cultural Plaza project will start on September 30. In the next work, I will closely focus on the overall plan of the company, complete my work in a practical way, work harder, make progress, and improve my work ability, Be a qualified Wanli employee, strive to create greater benefits for the company, and better complete the work next year.
Long term acquisition of various types of distribution cabinets, year-round recovery of various power distribution cabinets, high-voltage distribution cabinets, low-voltage distribution cabinets, high-voltage switchgear, power distribution cabinets, compensation cabinets, capacitor cabinets, switchgear, switch boxes, old power boxes, voltage regulators, air switches, year-round recovery.
The key problem in its use is that the electrical parameters of the stress tube must reach the values specified in the above standards before it can work reliably. In addition, pay attention to filling the air gap out of the fracture of the semi conductive layer of the cable insulation with silicone grease to eliminate gas, so as to reduce partial discharge. The cross-linked cable will shrink greatly during operation due to poor internal stress treatment. Therefore, when installing accessories, pay attention to that the stress pipe and insulation overlap shall not be less than 20mm to prevent the stress pipe from separating from the insulation during shrinkage.
