Tefkot cable company was established in 1995 by Mr. Jugal Kishore, a graduate engineer from University of Roorkee ( now IIT Roorkee) in edition to industry of steel wire drawing running since 1971. Later in 2001 his son Mr. Gunjan Garg B.tech IIT Delhi joined hands and inducted various un folded sectors to the existing activities of the Company like PTFE Cables, floor Heating Cables etc. We are renowned as PTFE Cables Manufacturers from a long decades..
PTFE insulated equipment/ hookup wires are generally used for internal wiring of various electronic and electrical equipments and other electrical purposes. They are most suitable to use in equipments involving for high frequency signals. Uniformity of insulation thickness around the conductor and very low dielectric constant of PTFE enables the transmission of high frequency signals with minimized signal losses as compared to other wires resulting in high quality signal transmission. Wires are manufactured in conformance with JSS, mil-W, BSS specifications as desired.
In signal and control applications, there are situations when multiple wiring connections need to be used. For the purpose a single cable having multiple no of cores is better suited. PTFE Insulated Multi-core cables find use in almost every type of electrical, electronic and engineering industry. PTFE insulated multi-core cables are required especially for high temperature and high frequency applications.
PTFE insulated multi-core cables are available with screen or without screen. Screening is required wherever there is need to protect the transmitting signals from external electric and electromagnetic noises. The cables are available in various twisted configurations such as bunched twisting, multiple pair twisting and multiple triads twisting. Cables up to 100 cores can be made upon customer's request.
Cables can be overall shielded or all the cores can be individually shielded or specific no of cores can be shielded and rest can be kept unshielded as required.
PTFE Insulated Multi-core cables are jacketed to give mechanical strength and binding to the cable. The jacket can be of PTFE or PVC or Rubber as required. An Armoring of SS or GI wire braid can be provided over the jacket to give extra strength and durability to the cable.
The size of the electronic and electrical equipment is decreasing day by day bringing in the need of wires of smaller size so that they can be accommodated in reduced space in the equipment. In high voltage applications if size of conductor is reduced the corona (ionized discharge) is produced. This corona attacks the insulation and greatly reduces the life of insulating material. Hence to avoid the damage of insulation the conductor size has to be kept big which in turn limits the miniaturization process of the equipment. High voltage corona resistant (HVCR) cables remove this problem.
These cables are made by insulating the conductor with specially made corona resistant (CR) PTFE tape. CR PTFE tape has increased resistance to corona discharge which helps in making high voltage cables in reduced sizes.
The HVCR cables are available for voltages as high as 22 KV AC or 50 KV DC both with screen and without screen. Screened HVCR cables are recommended where electrical circuit in proximity of HVCR cable needs to be protected from corona..
Heat Resistant High Temperature (HR) Cables are used as power cables in plants where there is high temperature environment and ordinary PVC cables can not be used such as near rotary kilns, furnaces, boilers etc. Due to the high temperature around the furnace, the electrical wiring of motors , control panels etc. near the furnace gets damaged very frequently, which compels the replacement of cables at periodic intervals leading to precious loss of productivity. This problem is greatly reduced by using High temperature PTFE insulated H.R. cables.
H.R. Cables made by Tefkot Cable Company are made by using PTFE insulation which is a High Temperature insulating material having excellent electrical properties and is inert to almost all chemicals and it also does not age. These properties make it suitable to be used as power cable in industries such as steel, cement, fertilizer, chemical etc.
PTFE sleeves are made by tape wrapping and sintering process as per JSS and other specifications. PTFE sleeves/ tubings find there application in various sectors such as :-
PTFE sleeves are made available in various bore sizes ranging from 0.50 mm to 25.00 mm in different wall thicknesses. Common wall thicknesses are 0.25 mm, 0.30 mm, 0.40 mm and0.50 mm. PTFE sleeves are available in 11 solid colours and various combinations in bi-colour and tri-colour as per requirement.
PTFE is known to be the best dielectric for RF (Radio frequency) coaxial cables. The essential function of coaxial cables is to transmit high frequency energy and signals with low loss, with reflection less matching and without Phase and Amplitude distortion.
The problem in high-energy transmission is the losses because of i) cable dielectric, ii) cable construction, iii) radiation, and iv) interference with adjoining circuits. The coaxial cable construction has been invented to overcome these problems, in which signals and energy are contained within an enclosed space. It consists of a core conductor, surrounded by pure PTFE dielectric covered with a metal shield, and finally encased in an overall jacket. The shield provides the return path as well as the confinement for RF energy, and is generally grounded.
Where ever the temperatures are involved, they need to be measured, monitored and controlled. One of the common methods for the purpose is the use of thermocouples.
When the thermocouple comes in contact with heating object, an emf is generated between its two wires which is proportional to the temperature of the object. Temperature indicator senses this emf and displays the corresponding temperature.
Thermocouple extension cables are the lead wires connecting the thermocouple and the temperature indicator. Conductors of these wires are of same metal as that of Thermocouple and hence are quite costly.
