A cable duct is a form of housing for a run of cables that has to pass a traffic area such as a doorway or be run up a wall without being seen. Depending on the environment and the intended use, the cable duct can be manufactured out of a number of materials. Materials range from plastics of any color
A surge arrester is a device to protect electrical equipment from over-voltage transients caused by external (lightning) or internal (switching) events.
Also called a surge protection device (SPD) or transient voltage surge suppressor (TVSS),
A surge arrester is used to protect equipment in power transmission and distribution systems. (For consumer equipment protection, different products called surge protectors are used.)
The insulators are unbreakable and have electrical and mechanical properties that allow them to be used even under difficult working conditions, such as at high room temperatures, in contact with corrosive substances, during vibrations, and so on. They are made from red polymer glass-polyester material, reinforced with glass fibre, and are self-extinguishing. The hexagonal middle layer with two opposite sides makes attaching and engaging the insulator easier. On request, the insulators can also be supplied in the following designs: – With a thread not conventionally used in mass production – With one or two “GB” threaded bolts
Indoor voltage divider insulators are used for the detection of the presence of voltage on phase lines. The basic operation principle is on the capacitive division of phase voltage. The voltage divider insulators are used with capacitancecoupled voltage indicating system. They are suitable for temperatures from -25°C up to +90°C.
is a shrinkable plastic tube used to insulate wires, providing abrasion resistance and environmental protection for stranded and solid wire conductors, connections, joints and terminals in electrical work. It can also be used to repair the insulation on wires or to bundle them together, to protect wires or small parts from minor abrasion, and to create cable entry seals, offering environmental sealing protection. Heat-shrink tubing is ordinarily made of polyolefin, which shrinks radially (but not longitudinally) when heated, to between
A thermostat is a regulating device component which senses the temperature of a physical system and performs actions so that the system's temperature is maintained near a desired setpoint. Thermostats are used in any device or system that heats or cools to a setpoint temperature.
The Hygrostat is designed to control the relative air humidity inside of enclosures. When connected to an enclosure heater, (de-humidifier), it will turn the heater on at the set humidity level in order to raise the dew point. This helps prevent damage and malfunction of electronic components caused by condensation and corrosion.
