Feature:

1,it has characteristic of strong moisture absorption,big expansion rate and quick expansion velocity.

2,small resistance can make cable has semi-conductivity and weaken the electrical field strength effectively.

3,high mechanical strength makes it easy to be wrapped and longitudinal wrapped for kinds of cables.

4,it is heat-resistant and can bear high instant temperature.cable with this product can keep stable performance at instant high temperature.

Storage:

it should be stored in dry house,kept away from source of fire and not to be exposed to the sunshine.the shelf life is 6 months after the manufacturing date.also it should avoid moisture and mechanical damage during storage and transportation.

Q:What is the difference between a kbg threading pipe and a PVC threading pipe?
You should be said: 2-way cross-linked polyethylene insulated PVC sheathed cable 4 core 185 square millimeters, SC is steel pipe, diameter . FC is laying method dark cover the floor or floor. Personal opinion, hope to help you!
Q:Home leaked, installed in the floor below the wire was blisters will have any security risks? How can the water inside the pipe to dry
Megohmmeter, such as measuring insulation normal, that is, induction power, the other line after grounding, the pen measured no electricity.
Q:What kind of KVM switch is this configuration below?
Wire and cable warranty period is 30 years of national warranty period. But the specific warranty period according to the type of wire and cable and the use of conditions and temperature and applicable methods to determine. General cable maintenance period is about 15 years, but to ensure that the normal use of the environment, such as the amount of temperature is below 70 degrees, but you are more than 70 working environment to use, of course, may not be used for a year. Therefore, the most important thing is to follow the instructions to use.
Q:Is the toilet wire walk on the ground? Are there any hidden dangers?
The proportion of the cross-sectional area of the cable through the embedded pipe is 20%
Q:Cable YJV-3 * 70 + 2 * 35 general wear large SC tube? Ask you.
Charging line and the phone does not match, for the good point of the line just fine
Q:Where should the inner diameter of the plastic tube of the cable be at least the number of times the outer diameter of the cable?
Not allowed to slot the proposal with PVC gusset which is only 1 cm thick only open protective layer on it! The water pipe is not enough unless you have a thickened wall outside the decoration.
Q:Building decoration wiring pipe elbow with yellow wax tube can you?
The control cable transfers the electrical energy from the power distribution point to the power supply lines of the various electrical equipment The rated voltage of the power cable is generally 06 / 1kV and above, the control cable is mainly 450 / 750V The same specifications of the power cable and control cable in the production, the power cable insulation and sheath thickness than the control cable thick
Q:Buy Taipower c 450P with remote control to add audio and video cable
And I answered the other person's question is very similar: . the line of the banding distance of not more than 1.2 meters, the two ends of the wire box outlet tube 15CM should be ligation; . casing embedded, then through the basement wall, the surface must be installed rigid Waterproof casing, that is, steel pipe + water ring; through the fire pool, living pool: flexible waterproof casing; (wing ring specific practices can be collected online related Atlas); through the floor, according to whether the design requirements , Under normal circumstances PVC casing on it. Note: . rigid waterproof casing, flexible waterproof casing is a one-time reserved in place, through the floor of the casing of the flower lamb to suppress the barge of Xi Jie Xi Xi shou, is the first stay hole, when the installation of riser Casing, because the floor casing has every layer, the location of the reservation will always be biased, in order to ensure vertical vertical pipe, and finally unified hanging line repair hole and then install the riser and casing. . now most of the bathroom are dirty, waste and diversion, and more of the riser, and so on, the air conditioning casing of all the shear wall should be embedded, to avoid the subsequent damage to the structure of drilling (no stay can only drill) Note that the location of the hole and the installation of the riser will affect the opening of the toilet window. . the casing is the casing, riser is the riser, casing than the riser model 1 to 2 level. . plate at the end of flat, board 2 to 5CM higher to see if you need to do leveling layer.
Q:Help look at such a configuration will not have compatibility issues! Do you need to improve? Budget in 5500 or so
What do you want to do? Do network cabling buried? Or in the building after the tube?
Q:What is the current good computer configuration on the market? The price of 4000 yuan or so no more than 4000 assembly parts to write down the price Thank you.
No way to save money! Moreover, the signal to you there, almost all attenuation finished.
