MKESH cable: description, purpose, technical characteristics of the product
The MKESH cable refers to structures frompolyvinylchloride with copper shielded braid and conductive tinned cores. It is widely used in automatic telephone communication systems in our country.
MKESH-cable is actively used in circuitscontrol and measuring equipment when creating switching electrical connections. And also in many automatic low-current control systems with the use of computers and computer equipment, in industrial television, in numerous types of telecontrol systems and CCTV. When creating all of the above structures and networks, conductors of MKESH brand are designed for direct (fixed) electrical connection of devices and devices with terminal junctions on communication crosses by soldering wires. It should be noted that there are modifications of this cable, which are designed to disconnect a variety of FM-type sensors - with a digital signal.
Technical and operational characteristics
MKESH cable can be usedin systems with a constant electric current,voltage of which should not exceed 750 V, and with alternating current with voltage up to 500 V. The maximum frequency is 400 Hz. The operating temperature of such a conductor is in the range from -50 to +50 degrees Celsius with relative humidity within 98%, and in conditions of mounting bends - not less than -15 degrees. The permissible continuous heating temperature of the conductor is 70aboutFROM. With a single laying, the MKES cable does not spread combustion. During assembly work, the radius of the bend to be taken into account must be taken into account, it must be within five outer diameters of the product. At an ambient temperature of 20 degrees, for different cross sections of its conductors, the resistance does not exceed 0.1 MΩ / km. This product is characterized by a design that is resistant to shock, as well as periodic mechanical stress and to prolonged vibration loads, both permanent and temporary. The manufacturer guarantees the operating life of the product in 10,000 hours.
MKSESH cable construction
Each conductive core is astranded copper tin plated conductor. The number of which can vary depending on the type from 2 to 14. Each vein is covered with fireproof insulation made of PVC plasticizer. All veins along the length of the conductor are twisted together. Each pair has its own color. A special synthetic film is applied to the core over the separation layer. The shield of the cable consists of a copper wire, it is not subject to various electromagnetic disturbances. Thanks to this, high-quality and stable operation of the product in telephone networks is ensured. Before installation, the MKSESH cable must be terminated with an obligatory waterproofing.
How much does the cable cost?
The price of such a product depends on many factors,of which the type of wire and the volume of purchased products will be the main ones. The average cost of the MKESH-conductor with two conductors will be 7-15 rubles per meter, and the option with 14 cores will cost in the range of 60-90 rubles.
