Waterproof Flame-Retardant Prefabricated Branch Flexible Low Voltage Power Cables
Waterproof Flame-Retardant Prefabricated Branch Flexible Low Voltage Power Cables
1.Product standard
JG/T147—2002 and Enterprise standard
2.The product possesses fine power supply reliability
(1) There is no joint on main cable’ s conductor, so it has a good continuity while fault points being reduced.
(2) The joints of prefabricated branch cable have been manufactured by whole factory-used mechanical equipment so that the instability caused by human factor will be greatly reduced.
(3) The Japanese advanced technology has been introduced for designing branch joint structure, the contact resistance of it is very small and never be influenced by heat expansion or cold shrinkage.
(4) The branch joint is shaped in a short time, so changes of contact resistance, caused by oxidation because the conductor being exposed in the open air for long time, can be completely avoided.
3. Electric Distribution, Flexible Selection and Free Combination
(1)As compared with bus-bar groove, it can reduce the engineering cost while its technical and economic targets are so high and comprehensive economic benefits are obvious.
4. Various Specifications, Flexible Selection and Free Combination
(1) main cable from 10mm2 to 630mm2; branch cable from 6mm2 to 400mm2, freely combined.
(2) A variety of cables, such as FZ-VV, FZ-ZR-VV, FZ-NH-VV, FZ-YJV, FZ-ZR-YJV, FZ-NH-YJV, FZ-WDZ-YJE, FZ-DL-NH-YJV etc, all of them can be selected according to different requirements.
(3) Branch cable can be installed in the light of building conditions.
5. Low Environment Requirements for installation, Easy for Construction
(1) Occupying a small area, the product is nice for the effective use of construction area, while it needs only a limited space in construction.
(2) Both its requirements for environment conditions and installation precision are very common.
(3) It can be installed easily and one winder is enough for installation; and its installation period is also very short, it only needs 5%-10% installation hours of that of bus-bar groove, with low labor strength.
(4) Due to its bending radius is small, the installation difficulties of such product will be greatly reduced, and the occupied space is also small.
6. Excellent Vibration Resistance, Air-Tightness, Waterproof and Refractory
(1) Fine Vibration resistance: When the joint of bus-bar groove is connected with machinery, looseness of especially, no measures should be adopted when the cable passes the settlement joint of building.
(2) Fine air-tightness and waterproof: the product can work normally in a wet circumstance and also can be laid in the open air or underground.
(3) “NH” type of prefabricated branch cable is adopted, so 90 min of normal power supply still can be kept under firing.
7. No Maintenance
(1) If the prefabricated branch cable is correctly installed following the relative requirements , its one-time cutting-in function is effective.
(2) The normally operated prefabricated branch cable is no necessary to make any maintenance.
