Pre-branched multi-core cable

In order to adapt to the development of residential buildings and the valuable opinions provided by the majority of electrical designers, Shandong Yanggu Haohui Cable Co., Ltd. has developed a new generation of three-phase five-wire multi-core prefabricated branch cable series products on the basis of single-core prefabricated branch cables. It is mainly used in the lighting system of multi-storey buildings. Due to the large appearance and heavy weight of the multi-core cable, the outer diameter of the prefabricated branch cable is larger, which will cause difficulties in laying. Therefore, the largest multi-core prefabricated branch cable currently produced by our company is limited to 240mm2 and below. Varieties are flame retardant, clean, fire-resistant and other different rules

    In order to adapt to the development of residential buildings,As well as the vast number of electrical designers to provide valuable advice,Shandong Yanggu Haohui Cable Co., Ltd. on the basis of single-core prefabricated branch cablesIt has also developed a new generation of three-phase five-wire multi-core prefabricated branch cable series products. It is mainly used in the lighting system of multi-storey buildings.

    Due to the large appearance and heavy weight of the multi-core cable, the outer diameter of the prefabricated branch cable is larger, which will cause difficulties in laying. Therefore, our companyThe largest multi-core prefabricated branch cable currently produced is limited to 240mm2and the following products. Varieties are flame retardant, clean, fire-resistant and other different specifications.         

    At present, the main cable section of multi-core prefabricated branch cable is6 mm² -50 mm² branch line section is 4square millimeter-When 25 mm². Single-core branch cables can be prefabricated for multi-core cables;35Square Millimeter -50Square millimeters. Can be multi-core cable prefabricated singlecore branch cable; main cable section in70square millimeter-240square millimeter,Branch section is 4When the square millimeter is 50 mm², multi-core cable can be prefabricated multi-core branch cable; if the branch section is larger than 50 mm², multi-core prefabricated single-core branch cable can be selected. The main cable can be two-core, three-core, four-core, five-core, branch line can also be two-core, three-core, four-core, five-core and other arbitrary combination.

    Carrying capacity of multi-core prefabricated branch cableSame as multi-core cable.

    Note: ① The rated voltage (U0/U) is 0.6/1KV.
    ② The trunk and branch cables are sheathed in black.
    If the branch cable requires the use of color (yellow, red, green, light blue, yellow/green) BV-500 type wire, should be specified in the order.
    The cable representation method is: model, voltage grade, trunk cable section, branch cable section
    For example: the main cable insulation is cross-linked polyethylene insulation, PVC sheath, conductor cross-section is 240 mm2, branch cable insulation is cross-linked polyethylene insulation, PVC sheath, conductor cross-section is 35 mm2,
    It is expressed as: YFD-YJV0.6/1Kv(1 × 240)/(1 × 35).
    Ordering Instructions    
    Please provide the following materials
    1. The length of the vertical main cable and each branch cable in the system diagram, and the arrangement of branch connections.
    2. Distribution system single-phase two-wire, single-phase three-wire, three-phase three-wire, three-phase four-wire and three-phase five-wire.
    3. Vertical main cable (XLPE/PVC cable) cable model, single core or single core twisted wire, wire size.
    4. Wire size of branch cable (XLPE/PVC single-core cable).
    5. The laying method is pulled up from the ground or dropped from the roof.
    6. Whether the upper end support is supported by cable clamping device or suspension insulation device.
    7. Attach attachment fixture, bracket, etc.
    8. Other items you think you need.
    Laying construction method     
    1. Place the cable reel on the pay-off rack (usually the cable reel is placed downstairs and the cable is pulled up).
    2. The rope for lifting is connected with the cable through the winding machine, and the winding machine is started to lift the cable up.
    3. When the cable net sleeve for lifting reaches the roof, hang the net sleeve on the hook prepared in advance.
    4. Fix the middle part.
    5. Connect the end of the branch line to the ammeter or the current interrupter.
    6. Connect with the horizontal trunk line or the main trunk line version.
    Attention during construction
    1. Confirm whether the prefabricated branch part can safely pass through the through hole;
    2. Take preventive measures to prevent the branch part from being damaged by the through hole during the lifting process;
    3. Do not apply tension to the branch cable during the lifting process;
    4, the use of lifting rope strength should be more than four times the weight of the cable;
    5. After the cable is lifted, it should be fixed immediately with appropriate methods to prevent the cable from falling off and being damaged;
    6. It is forbidden to use iron clamp for single core cable.
