Yanggu cable manufacturers in the role of oil
With the development of China's central and western regions, the development of the oil industry has become increasingly prominent. in addition to launching the "west-to-east gas transmission" pipeline, a large oil field "hope of hope" is also being developed ".Yanggu cable manufacturersIn addition to a large number of general-purpose cables for infrastructure, special cables for the petroleum industry will also be developed. This isYanggu cable manufacturersThe cable industry provides opportunities to develop new varieties.
At present, there are not many Yanggu cable manufacturers for China's petroleum industry. Mass-produced products include medium and deep well logging cables, submersible pump cables, etc. Trial production of ultra-deep well logging cables, high temperature oil pump cables, submersible halogen pump cables, small diameter logging cables, integrated logging cables, perforated cables, heating cables, electrode system cables and ultrasonic oil production cables, etc., may be produced in large quantities by ultrasonic cables, perforated cables and heating cables.
Yanggu cable manufacturersThe performance margin is very large. The key quality problem is that the quality of the double steel wire armor is not good, which will cause the casing and lantern cover to loosen, thereby damaging the cable, especially when the perforation produces violent shaking, it is more likely to produce loose casing or knot. For double-diameter steel wire armour, the steel wires should be selected and matched with the stranding pitch of the two layers to minimize internal stress. Yanggu cable manufacturers improve the quality of armor by referring to the methods used by logging cables for armor quality. The demand for such cables is in the order of thousands.
Yanggu power cable manufacturers,Yanggu wire and cable manufacturersLet me tell you that the performance margin of domestic cables is very large. The key quality problem is that the quality of the double steel wire armor is not good, which will cause the casing and lantern cover to loosen, thereby damaging the cable. Especially when punching holes, there will be violent shaking, which is more likely to produce loose sleeves or knots. For double-diameter steel wire armor, Yanggu cable manufacturers should select steel wires and match them with the two-layer stranding pitch to minimize internal stress.
What are the main points of purchasing wires and cables? Let's take a look. As the main carrier of power transmission, wire and cable are widely used in electrical equipment, lighting circuits, household appliances, etc. Its quality directly affects the quality of the project and the safety of consumers' lives and property. There are many wire varieties on the market, and appropriate wires should be used according to their own power load.
What are the precautions for wires and cables? Let's take a look. Common cable faults: wire surface markings-according to national standards, the wire surface should have continuous markings of the manufacturer's name, product model and rated voltage. This helps to find the manufacturing plant in time when there is a problem during the use of the wire, and consumers should pay attention to this when buying the wire.
There are many kinds of wire and cable products for electrical equipment on the market, which are difficult for ordinary consumers to distinguish. So what are the main categories of wire and cable products? What are the product naming principles of wire and cable? The editor brings you a brief understanding of relevant content knowledge.
The wires and cables for electrical equipment are mainly used for internal or external connection of electrical equipment, low-voltage transmission lines and various electrical signal transmission lines. Generally speaking, except for power cables, communication cables and magnet wires, most insulated wires and cables are classified as wires and cables for electrical equipment.
Electrical equipment with wire and cable is a large class of wire and cable products, a wide range of applications, many varieties, many series, large output, process type complex. The rated voltage of wires and cables for electrical equipment is low, and the working voltage is 450/750v and below, which is not more than 0.6/1kv. The working voltage of signal and instrument cables is usually 300/500v and below. The ampacity of the cable is determined according to the requirements of the cable.
Low voltage power cable winter pay attention to matters? As the weather gets colder and colder, manufacturers of low-voltage power cables usually become more difficult, which brings inconvenience to construction. Here are some precautions for winter construction. Let us take a brief look.
