Product Description:

0.6/1KW PVC insulation, cross-linked polyethylene insulated fire-resistant cables
I. Product Properties:

As for fire-resistant cable, GB/T12706-2002 standard may be the reference. Fire-resistant properties should be in line with GB/T18380-2001 standard.
This product use fire-resistant mica as a fire-resistant layer and its sheath is made from flame-retardant PVC sheathing material.
II. Characteristics of usage:
This product is applied to power distribution lines with AC rated voltage of 0.6/1kv and below and the occasions with the need of fire-resistant properties.
When the cable is laid, the ambient temperature should not be less than 0 ℃, and the minimum bending radius is 15 times the outer diameter of the cable.

Q:What is the heat of the cross-linked cable?
General model: SYV75-X (X on behalf of its insulation diameter 3mm / 5mm, the greater the larger the diameter of the larger) SYV S --- coaxial RF cable, Y --- polyethylene, V --- poly Ethylene
Q:How to effectively reduce the cost of car wiring harness?
The bottom edge of the bridge after bending (bottom bevel) and the width of the bridge can be the same length, but the range is controlled at 100-400mm, select the length of the two points, in the bridge side to help out on the side Two vertical lines, selected bridge bending direction as the cutting opening side; open the opening side as the bottom edge to draw the two vertical lines were used as two isosceles triangle in the sub-line, the waist triangle Edge length of the formula for the L = 2 × (bridge height × sin22
Q:How to connect the power cable pre-branch connector
In the pre-measured size cut out the jacket and insulation, according to the different cross-sectional size of the cable cut the size of the jacket and insulation different; with C-shaped tube corresponding to the corresponding color sequence crushing the trunk and branch lines, crimping attention to crimping The strength of the clamp, can not be too loose or too tight, too loose will cause the cable crimping off, resulting in open circuit, crimping too tight will break the conductor or cause the conductor stranded in the contact with a good conductor with polytetrafluoroethylene With the winding baking transparent, and then wrapped waterproof tape (tiger belt) can be used after the wooden hammer shrink the cable core to facilitate injection molding in the injection process should choose the appropriate mold and injection molding machine injection mold injection, the mold is too large cost Waste, the mold is too small caused by defective, bad seal at both ends of the running coke, affecting the injection effect
Q:Whether high voltage cables can be built in belt corridors
When the short circuit occurs when the wire through a large current, more than the rated current of the wire, so the wire will heat
Q:With the patch panel how to deal with the line corresponding to the crystal line of the line order is what
Although there is a relatively thick cable inside the cable to prevent a very thin cable was broken, but the insulation is not iron, after all, is generally a VB tube is also a corrugated pipe PVC pipe is also too iron
Q:How long is the service life of the cable?
cable bridge and other pipes and other facilities shall not share a column (bracket)
Q:PVC pipe on the GV.215-16 (C) What does it mean
SC pipe welding fluid with welded steel pipe, the general thread connection, or casing welding connection. TC pipe is a thin-walled steel pipe, referred to as wire tube, you can thread connection, tight connection, buckle type connection, not casing welding connection.
Q:The difference between power cable and overhead cable
His answer is correct! There is overhead cable generally use aluminum core conductor! Because light weight Overhead cable under normal circumstances are 6kV below the cable! If the voltage level is high, you need to do special craft production!
Q:Power cable casing buried what are the requirements
2 no protective measures, should avoid the termite damage zone, heat source and vulnerable to external damage to the section
Q:What are the lines that need to be set up for notebooks?
YJV cable is cross-linked polyethylene insulation, VV cable is PVC insulation, the former temperature level higher than the latter, such as the former conductor temperature can be 90 degrees, while the latter can only to 70 degrees!
