Overview of Cables and Wires in the Borescopes
One of the main cables you get to see in the Borescopes is the push type which extends up to 40 meters and beyond. This is primarily based on spring coil with unbreakable features. Some of the Borescopes have the cable length extending up to 300 meters. Using such cables it is possible to send the device long way through the pipes and closed structures for remote inspection. The push cables have a protective sheath which encloses data cables for the transmission of clear images to the visual display units. The diameter of the push cable varies from 1mm to 4mm and beyond depending on its length and strength. The core of the push cable sheath is made of highly temperature resistant material that repels heat, keeping the entire cable under moderate temperature.
Borescopes Main Cable
The main cable in the Borescopes is made of tough surface coating and multiple layers of hardened plastic and metallic alloy combination. Since this is the cable which carries the entire weight of the Borescopes and endures the highest levels of pressure (within the pipes and tubes carrying high pressure liquids), it is made to be tough and flexible in nature. This has high resistance to temperature variations within the extreme conditions to which it gets exposed. The tensile strength of the cable is also very high as it needs to keep the Borescopes under control without breaking apart.
Borescopes Optical Cables
The most important types of optical cables used in the Borescopes are made of optic fiber. You can see many of them grouped into bundles around the LED lamps at the probing handle edge. They help in optimizing the intensity of the lamps through sensitive controls. They also protect the LED from exploding under high temperature and explosive conditions.
The other set of optic cables can be seen near the eyepiece/ camera region. They are used for enhancing the image intensity when it gets transmitted from the lens into the camera region and subsequently into the display unit. Intelligent Borescopes have the options for controlling the brightness of light through these cables for optimizing the daylight readable display unit brightness.
Borescopes Power Cables
Most of the Borescopes power cables are routed through the battery storage units. They supply DC power to the different components and parts of the device. The standard type of devices might have single switch control, while the advanced devices come with multiple switch control for the different components. This helps in conserving the battery power by avoiding the inflow of power to the parts which is currently idle. They are made of lightweight aluminum with fiber coating to reduce the overall weight of the Borescopes.
Borescopes Data Cables
The data cables in the Borescopes are laid out between the lens, camera and the display units mainly. The other electronic and electrical components are linked to the control panel unit. Since the modern Borescopes have the control panel built into the display unit, the cables serve the multiple purposes of sending images to the unit and receiving commands from the panel.
