Application area of U/UTP Cat 5e PVC ng(A)-LSLTx:
High-frequency twisted-pair cables for structured cabling systems are intended for fixed horizontal and vertical installation taking into account the fire load of cables in buildings such as kindergartens, schools, hospitals, boarding schools and nursing homes, where the use of cables that do not propagate flame during group installation according to Category A with a low-toxicity PVC jacket with low smoke and gas emission in accordance with GOST 31565-2012 is required. The cables are designed for operation in the frequency range up to 100 MHz (Category 5 and 5e according to GOST R 54429-2011 and ISO/IEC 11801). The cables are manufactured in climatic version U, installation categories 3 and 4 according to GOST 15150.

Operating and installation conditions:
Cables may be operated at ambient temperatures from −40 to +60°C. Cable installation is permitted at temperatures not lower than −10°C.
The minimum permissible bending radius during installation and laying shall be at least 8 times the maximum outer cable diameter.
Reliability requirements:
The minimum service life of the cables, provided that the consumer complies with the established installation rules and operating, storage and transportation conditions, shall be at least 25 years. The service life is calculated from the date of cable manufacture.
