kabloya zirxî: Ew ji hêla rêgirên maddî yên cihêreng ve di nav kelekek metalî ya bi materyalên îzolasyonê de tê saz kirin, û di nav kombînasyonek zexm a guheztinê de tê hilanîn.
Kabloya ne-zirxî: kabloyên bê qatên parastinê yên zirxî, ji çend an çend komek têlên di her komekê de herî kêm du kabloyên zivirî, her komek têlên îzolekirî, gelek caran navendek Twisted dorpêç dike. Tevahiya nanê derve xwedan qatek vegirtinê ya pir îzolekirî ye.
Abstract: Introduce the materials and structures of environmentally friendly mineral insulation fire cables, through designing mineral fire prevention insulating layers, thermosetting polymer protective layers, inorganic fiber filler, low smoke halogen-free silicon porcelain insulation layer, metal armor fireproof layer, fire prevention layer, and metal armor fireproof layer. The composite refractory structure is composed of low -smoke halogen-free environmental protection external care layer, realizing the environmental protection of cable fire resistance and low toxic environmental protection performance, low toxicity, and fire-resistant cable.
Ew transmission line connection point is a major weak point of inline operation. In the operation of often heat burned, thus causing power outages. The analysis of the wire connection point heating problem, and timely adoption of appropriate preventive measures, will effectively avoid the wire connection point overheating. This causes the wire connection point to burn off the accident. Analyze the causes of wire connection point heating, and understand the theoretical basis for the temperature rise of high-voltage lines. Vê bigire, mastering the prevention and solution measures to deal with the connection point heating problem, to ensure the safe and reliable operation of the line has practical significance.
Avakirina kabloya fiber optîk bi gelemperî li gavên jêrîn têne dabeş kirin: amadekarî → projeya rêvekirinê → danîna kabloya fîber optîk → berhevkirina kabloya fiber optîk → pejirandina projeyê.
Ew zinc oxide arrester uses zinc oxide resistance as the main component, which greatly improves the voltammetric characteristics of the arrester and increases the through-current capability. When the arrester is in normal operation, the voltage flow through the arrester current is only microampere. When the overvoltage is received, the excellent non-linear characteristics of the arrester play a good role.
A lightning arrester is mainly used to protect electrical equipment from lightning intrusion overvoltage and operating overvoltage on its power equipment insulation damage.
The insulation material of wire and cable is an important structure to ensure the proper operation of the conductor. The operating life of the insulation material is an important indicator of the life of the cable. Usually, what are the insulation materials we use for wire and cable?
High-voltage line arrester for 6 ~ 220kV AC transmission lines, is a new type of lightning arrester suspended and installed on the transmission tower.
Di rewşê de çêkirina xeta voltaja bilind-voltaja, Pir kesên ku li ser projeyan dixebitin bi gelemperî li ser hevokên kabloyên hêza voltaja bilind têne. Îro, Ez dixwazim nîqaşên cûrbecûr yên li ser xêzên kabloyên hightaja bilind û serlêdanên wan bi we re nîqaş bikim. Yekem, Ka em li ser çi bipeyivin Kulîlkên kabloya hêza voltaja bilind yet.
Rola sereke ya heat shrink tubing in a circuit is to protect important devices and circuits from damage and impact. Although it does not have any particular impact on the operation of the circuit, it is often the key point that determines the success or failure of the entire design. With the rapid development of the electronics industry, flame-retardant heat shrink tubing is also inseparable from the electronics industry, more and more electronic products need to use flame retardant heat shrink tubing for protection. The flame retardant processing of the heat shrink tube, when attacked by external fire sources, can effectively block, delay or stop the transmission of flame, to achieve the effect of flame retardant.
Li heyî, overhead cables are used to transport electricity over long distances. Conventional cables are mostly aluminum conductor steel reinforced (ACSR). Since the 1990s, carbon fiber composite cores (aluminum conductor composite core) have been used as the core bar of cables. ACCC has the following advantages over traditional conductors.
