Description
Technical Field
The invention relates to the technical field of cables, in particular to a wall-attached self-fixing type strong-current cable.
Background
Definition of cable 1: a wire made of one or more mutually insulated conductors and an outer insulating protective layer for transmitting power or information from one place to another; definition 2: typically a cable like rope made up of several or groups of conductors (at least two in each group) twisted together, with the conductors of each group being insulated from each other and usually twisted around a center, and being entirely surrounded by a highly insulating covering, the cable being characterized by internal electrical conduction and external insulation.
The strong electricity refers to the electric power part in the field of electrician, and is characterized by that its power is large, current is large, frequency is low, and it mainly considers the problems of small loss and high efficiency, and its relationship with weak electricity is very close, and is opposite to "weak electricity", and strong electricity and weak electricity are opposite concepts, and in the conceptual sense, it mainly differs in application, but can not only define their relationship by voltage (if it does not need to specify voltage to distinguish them, it can define above 36V (human body safety voltage) as strong electricity, and below 36V (human body safety voltage) as weak electricity, and both are related and distinguished, and the general distinguishing principle is that the processing object of strong electricity is energy source (electric power), and is characterized by that its voltage is high, current is large, power is large, and frequency is low, and the main problems of reducing loss and raising efficiency, and the processing object of weak electricity is mainly information, i.e. transmission and control of information, the method is characterized by low voltage, low current, low power and high frequency, and mainly considers the effect problems of information transmission, such as fidelity, speed, breadth and reliability of information transmission, and the method is roughly distinguished as follows:
the cable body (1) has different AC frequencies
The frequency of the strong electricity is typically 50Hz (hertz), referred to as "power frequency", meaning the frequency of the industrial electricity: the frequencies of weak current are often high or very high frequencies, measured in KHz (kilohertz), MHz (megahertz).
The transmission modes of the attached pad (2) are different
The strong electricity is transmitted by a power transmission line, and the weak electricity is transmitted by a wired line or a wireless line. Radio is transmitted as electromagnetic waves.
(3) Different magnitudes of power, voltage and current
The strong electric power is measured by KW (kilowatt), MW (megawatt), voltage is measured by V (volt), KV (kilovolt), and the current is measured by A (ampere) and kA (kiloampere); the weak current power is measured in W (watt) and mW (milliwatt), the voltage is measured in V (volt) and mV (millivolt), and the current is measured in mA (milliampere) and uA (microampere), so that the circuit can be formed by a printed circuit or an integrated circuit.
High-frequency (hundreds of KHz) and medium-frequency equipment exist in strong electricity, but the voltage is higher, the current is also higher, due to the development of modern technology, weak electricity permeates into the field of strong electricity, such as power electronic devices, wireless remote control and the like, but the weak electricity can only be calculated as a weak electricity control part in the strong electricity, and is different from the controlled strong electricity, according to the fundamental principle that the weak electricity conducts signals and electric energy, the strong electricity and the weak electricity can be easily distinguished, for example, although the electricity consumption of an electric shaver, a flashlight and the like is only two dry batteries (3V), but the electricity consumption cannot be regarded as weak electricity because the voltage and the current of the electricity consumption are small, because the electricity consumption is conducted but not signals, the electricity consumption belongs to the strong electricity category, generally refers to power supply and distribution systems such as a mains supply and distribution system, including an air conditioning line, an illumination line, a socket line, a power line, a high-voltage line and the like, weak current is mainly classified into two types: one is low-voltage electric energy with safety voltage level, control voltage and the like specified by the state, the electric energy has alternating current and direct current, such as a 24V direct current control power supply or an emergency lighting lamp standby power supply, the other is an information source carrying information such as voice, images, data and the like, such as audio, video circuits, network circuits and telephone circuits, the direct current voltage is generally within 36V, and electric appliances such as telephone, computer and television signal input (cable television circuit), sound equipment (output end circuit), broadcasting system, building automatic control (such as entrance guard and security protection) in household electric appliances are weak current electric equipment.
The cable laying refers to a process of laying and installing cables along the checked route to form a cable line. According to the use occasion, the method can be divided into a plurality of laying modes such as overhead, underground (pipelines and direct burial), underwater, walls, tunnels and the like. The reasonable laying mode of selecting the cable is all very important to transmission quality, reliability and construction maintenance etc. of guaranteeing the circuit, and a laying mode of forceful electric power cable is laid and is called and is obviously laid and establish the circuit, and obviously laid and establish the circuit and divide two kinds: a protective tube is laid along a wall; another kind does not wear the protection tube and lays along the wall, it is more common not to wear the protection tube and lays along the wall because of its cost is lower to lay simply, but lay along the wall and utilize the fastener more to fix, need be at wall chisel hole and need fix in many places, not only influence the wall aesthetic property, it is more to consume time simultaneously, the security also can not be guaranteed, cause the damage to the cable easily when fixed dynamics is great, lead to the cable to loosen when fixed dynamics is less, it is difficult to the fixed dynamics of accuse fastener
