Armored telephone cable HYAT22 is mainly used for pipe laying, but also can be used for overhead, but it needs to use hanging wire. HYAC type cable is only suitable for overhead, no need to use hanging wire and hook.
The armored telephone cable HYAT22 improves the mechanical strength and corrosion resistance of the cable. It can be laid in any way and is more suitable for direct laying in rock areas.
Armored telephone cable HYAT22 acid and alkali resistance, hydrolysis resistance, UV resistance, low temperature resistance, abrasion resistance, flame retardant CC46 bending radius: Flexible cable is different from ordinary fixed device cable. Please refer to the following device and precautions in the device: Towline cable The laying of the cable must not be distorted, ie the cable must not be unwound from either end of the cable drum or the cable tray. Instead, the cable must be rotated to unwind the cable, and if necessary, the cable can be unrolled or suspended. The cable used for this occasion can only be obtained directly from the cable reel. Attention must be paid to the minimum bending radius of the cable. The cables must be loosely laid side by side in the drag chain, separated as much as possible, and separated or penetrated into the separating voids of the support. The gap between the cables in the drag chain should be at least 10% of the cable diameter. Do not touch or get trapped together. Both points of the cable must be fixed or at least fixed at the moving end of the chain. The distance from the point of movement of the cable to the end of the chain should be 20-30 times the diameter of the cable. Make sure that the cable moves completely within the bend radius, ie it cannot be forced to move. This allows the cables to move relative to one another or to the guide. After a period of operation, it is best to check the location of the cable. The inspection must be performed after pushing and pulling. If the drag chain breaks, the cable needs to be replaced because damage caused by overstretching cannot be prevented.
Armored telephone cable HYAT22 product structure:
Conductor: TR type soft round copper wire conforming to GB3953, its nominal diameter is: 0.4, 0.5, 0.6, 0.7, 0.8, 0.9mm.
Insulation: Insulation grade high-density polyethylene or polypropylene, insulated wire according to the full color spectrum, identification and identification, insulation color in line with GB6995.2 regulations.
Pairing: Two pairs of insulated single wires of different colors are twisted into pairs at different pitches to minimize crosstalk and the specified chromatogram combination is used to identify pairs.
Core: It is made up of a number of basic units or super units. Each unit is wrapped around with a specified chromatographic tie to identify different units. 100% and more of the cables are equipped with 1% spare line pairs, but no more than 6 pairs.
Core wrap: Wrap the lock cylinder with a non-hygroscopic tape.
Aluminum-plastic bonding integrated jacket:
Shielding: Use a 0.30mm thick double-coated aluminum strip, wrapped longitudinally outside the cable peripheries, with laps greater than 6mm on both sides and bonded together, and use a corrugated longitudinal pack for more than 400 pairs.
Jacket: Black Low Density Polyethylene
A lot of introduction about the HYAT22 telephone cable
The telephone cable HYAT22 is a local telephone cable designed for telephone exchange areas and trunk trunks. It can be used to transmit digital signals at 2B+D and below for audio signals and integrated services digital networks, as well as for transmitting 2048 kbit/8 numbers. Signal or analog signal below 150KHz.
