Guangdong Jinlianyu Wire and cable The company is a professional manufacturer power cable Industrial enterprises of electric wire, whose products include high-voltage transmission Cable And low-voltage civil cables, which are used for power engineering and civil wiring. After years of careful operation, Jinlianyu wire and cable has become the preferred brand loved by local customers in Foshan for many years pin Quantity has always been the top spear!
In 2021, in response to the national policy of expanding domestic demand and facing the impact of the economic crisis, we will implement the "going global" strategy. We will explore markets and establish distribution networks in Guangxi, Hunan, Jiangxi, Anhui, Chongqing, Sichuan, Guizhou, Yunnan, etc!
Now Chongqing, Sichuan, Guizhou and Yunnan are looking for cooperative dealers in Jijiao. Sincerely welcome customers with certain financial strength and network. At the same time, customers with this intention are willing to negotiate and seek common development!
YJV cables sold directly by the manufacturer have complete specifications and are available from stock under full item warranty inspection. The products are manufactured in accordance with GB/T12706-2008 Extruded Insulated Power Cables with Rated Voltages from 1kV to 3kV. At the same time, they can also be manufactured according to the user's needs.
Yjv cable consists of inner and outer components, namely conductor, polymer ethylene Insulator, filler (nylon, pvc composite material, etc.), PVC outer sheath,
Among them, most conductors are copper cores. At present, copper conductors are widely used in the market, while aluminum conductors are seldom used due to poor conductivity and lack of standards; The filler is mostly made of nylon and plays a role in protecting the cable core, which is equivalent to putting a piece of "clothes" on the cable core; If it is armored power cable, a layer of steel tape armouring will be added between the filler and the sheath, so that the cable can be buried underground to play a compressive role. The model of steel tape armored cable is yjv22; PVC sheath is our common PVC material.
1. Purpose:
Low voltage cables are suitable for power transmission and distribution lines with AC 50Hz and rated voltage of 3kv and below.
2. Usage properties:
① The zui high rated temperature of cable conductor is 90 ℃.
② In case of short circuit (the long duration of zui shall not exceed 5 seconds), the high temperature of the cable conductor shall not exceed 250 ℃.
3. Precautions for installation: when laying cables, the small bending radius of zui shall not be less than 10 times of the outer diameter of the cable. The yjv/yjlv cable can be laid indoors, in trenches and pipes, or buried in loose soil, and cannot bear external forces. The yjv22/yjlv22 cable is laid underground and can bear the external mechanical force, but cannot bear a large tensile force. Suitable tools such as paying off rack and guide roller shall be used for cable laying to prevent mechanical damage and keep away from heat sources. When cables are laid through pipes, the inner diameter of the pipe shall not be less than 1.5 times of the outer diameter of the point. When multiple cables are laid through pipes, cable extrusion is prohibited. The total area of the cable shall not exceed 40% of the total area in the pipe.
Yjv cable product classification: ordinary type, flame retardant type, fire-resistant type, low smoke halogen free type
