What do you mean by cable layout?
What do you mean by cable layout?
Cable layout and routing has a critical effect at high frequencies and must be closely defined. A cable which is run close to the ground plane and in the opposite orientation to the measuring antenna, will radiate far less than one which is suspended in free space and aligned with the antenna.
How do you lay out cable?
Laying procedure
- A trench of about 1.5 meters deep and 45 cm wide is dug.
- Then the trench is covered with a 10 cm thick layer of fine sand.
- The cable is laid over the sand bed.
- Then the laid cable is again covered with a layer of sand of about 10 cm thick.
What are the parts of a mains cable?
An electrical cable consists of a conductor, which channels the electrical flow, and an insulation containing this electrical flow in the conductor….
- CABLE CONDUCTOR.
- CABLE INSULATION.
- CABLE METAL PROTECTION.
- CABLE OUTER SHEATH.
What are the three main parts of a cable?
Cables consist of three major components: conductors, insulation, protective jacket.
What are the four main types of cable?
The Four Types of Network Cabling
- Coaxial Cable. Coaxial cables have a single copper conductor at the center, while a plastic layer provides insulation between the center conductor and braided metal shield.
- Fiber Optic Cable.
- Shielded Twisted Pair (STP) Cable.
- Unshielded Twisted Pair (UTP) Cable.
What is types of cable?
Cables are classified into 5 types depending upon their purpose as follows:
- Ribbon Electric Cables. It consists of multiple insulated wires running parallel with one another and is used for transmission of multiple data simultaneously.
- Shielded Cables.
- Twisted Pair Cables.
- Coaxial Cables.
- Fibre Optics Cable.
How far apart should cable supports be installed?
One of the requirements for permanent wiring, and thus for temporary wiring, was the need for adequate support. Article 336-18 stated that cable must be secured in place at intervals not exceeding 4.5 feet (1.37 m) and within 12 inches (305 mm) from every cabinet, box, or fitting.
What is difference between LT and HT cable?
Application: LT and HT cables have various areas of application. LT cables can be used in industries like power distribution, power stations, railways, etc. revolving around 1.1 kV range. While HT cables are used in power transmission and distribution that has a range greater than 1.1 kV.
What is 3 core cable used for?
Three core flex: This type of cable is used to connect appliances such as lamps or extension cables to the power outlet sockets. The flex cable (flexible cord/cable) has three cores being Live, Earth and Neutral.
What are the two types of cables?
Which cable is used in LAN?
Cables are commonly used to carry communication signals within LAN. There are three common types of cable media that can be used to connect devices to a network and they are coaxial cable, twisted-pair cable, and fiber-optic cable.
