Product Description:

Name: 127/220kV, Cu/XLPE/Al corrugated/PVC 1*2500mm2, Optical Fiber sensing cable inserted.


Conductor shape: segments


Standard: IEC 60840-2004


IEC 62087-2006


Or equivalent DIN, BS, AS/NZS, JIS, ASTM, IS, etc. standard.


Package: Steel Drum


Additional Options: Flame retardant, Anti-termite.

Technical details:


 


Conductor: Conductor cross section of 800mm2 or below is stranded through compacting round core, with better roundness and higher compacting coefficient. Conductor cross section more than 800mm2 is made by segment of Milliken method to minimize skin connecting and alternating current impedance and increase power transmission capacity of cable.


 


Insulation: XLPE, gravity feeding in 1000 level ultra-clean environment.


 


Product line: VCV/CCV


 


Metallic screen/sheath: Option 1) Welded corrugated aluminum sheath


                                    Option 2) Extruded Corrugated aluminum sheath


                                    Option 3) Copper wire + poly laminated sheath


 


Outer sheath: PVC, MDPE, HDPE, LDPE


 


Characteristic of use:


  1. Allowable max. long-time operation temperature of cable conductor: 90°C

  2. Allowable Max. short circuit temperature of cable conductor (max. sustaining period not exceeding 5s): 250 °C 

  3. Allowable Min. bending radius when laying cable, generally 20 times of the cable diameter


 


Main Cross sections for 127/220kV Power Cable:


400mm2, 500mm2, 630mm2, 800mm2, 1000mm2, 1200mm2, 1400mm2, 1600mm2, 1800mm2, 2000mm2, 2500mm2


 


Quality and service:


 

Our motto: “Reputation based, Quality prioritized”, we wins customers trust for following reasons:


 

1, Quality control strictly follows ISO9001:2008 and ISO14001:2004, while guarantee that all products we supplied are totally new and unused. They are made of best material by first-class process techniques while tested and qualified by all specified testing items.


 


2, The Company promises to offer high-quality after-sale service to our customers. The service for cable fixation, installation and testing are available at customer request, if necessary technicians are sent to give instructions to the customers. After make sure it is the problem on quality we will repair or replace the defected products, the concerned expense or loss will be at our side.


 


3, The Company guarantees to deliver products in compliance with the bidding documentation.


 


4, The Company promises to offer cooperation and service according to the binding contract and requirements of supervision, testing for products.

Q:The computer host is always start to stop, resulting in the last can not start. What is going on?
GB-2002 provides: metal cable bridge and its bracket and the introduction or extraction of metal cable ducts must be ground (PE) or zero (PEN) is reliable, and must meet the following requirements:
Q:What is the interface between the power interface and the hard disk?
YCV-copper core XLPE insulated PVC sheathed power cable, VV-copper core PVC insulated PVC sheathed power cable. YJV-voltage level (kV) 6 ~ . the maximum allowable working temperature 90 ℃ VV-voltage level (kV) 1 ~ . allowing the maximum operating temperature of 65 ~ 70 ℃
Q:Power cable yjv22-10kv-3 * 50 what it means
Yj is cross-linked polyethylene insulation, v PVC sheathed 22 is double steel tape armored, voltage 10KV, 50 square three-core copper cable
Q:What is the length of the wire that affects voltage and electricity
When the cable is laid on the multi-layer bracket, the cables are arranged from top to bottom, the first layer is the high voltage cable, followed by the low voltage power cable. The control cable is placed on the lower part of the power cable. At the bottom of the instrument cable, when the low voltage power cable With the instrument cable in the same layer of laying, should be added partition isolation. Computer communication coaxial cable, full length are required to shield the use of closed trunking.
Q:Ipad charge does not enter the charge does not support this accessory charge
The In general, single-core 15 square wire, for lighting fixtures; single-core 2
Q:How to connect the power cable pre-branch connector
Pre-branch cable detection: a In addition to routine pressure test, it is necessary to increase the insulation resistance test, with a shake table can be completed in each branch after the completion of injection The table measures the insulation in the finished product After the pressure is also used to detect the insulation of the table to prevent the water cooling process in the branch of the water caused by short-circuit, the general AC voltage test can not detect, can only increase a set of table detection process B Core conduction detection, In each branch body should be tested with the trunk of the conduction test to prevent the production process due to improper operation caused by the branch and the trunk circuit
Q:The telephone line, TV line, cable, power lines are worn to a wire tube, what will happen?
This is the wiring of the cable wiring formulas: the next five is 10 square below the current per square 5A current wiring, one hundred and twenty is more than 100 square per square 2A, 25335 three circles, meaning 10 (Excluding) or more, 25 square feet per square 3A wiring, 35 square (inclusive) or more, 100 square (excluding) the following per square 4A line, that is, 25 square feet, 35 square feet per square by 3A or 4A wiring line.
Q:What is the power cable accessories used to do?
Do not know what you want to ask? What about your situation? Normal or pregnant? Normal this radiation does not affect what, if it is pregnant, this is far away from the best. Pregnancy is most needed to stay away from the microwave!
Q:Lighting wire, I do not know is it. The When to use BV1 * 2.5, when to use 2 * 2.5, when to use 3 * 2.5, when to use 4 * 2.5,
This is generally not very good replacement, and you ask is not very specific, the proposed problem is more clear, more convenient for you to answer.
Q:With the patch panel how to deal with the line corresponding to the crystal line of the line order is what
The size of the jumper varies with the specifications of the bridge, which is uncertain; the so-called repetitive ground is at least two that is the beginning and end of the end, if the length is enough, the need for intermediate isolation to do the appropriate length of the ground. Stressed that a certain attention to the ground is connected to the power grid on the ground, not directly into the ground.
