Product Description:

Waterblocking Yarn : Be used for communication cable、optical cable 、


The Star Material Water Blocking Yarn is made out of non-corrosive substances (without acids and alkalis), has fast water absorbing speed, high tensile strength and has good heat-resistance characteristics. This yarn is mainly used in communication cables, optical cables, power cables and marine cables for the purpose of binding, tightening and blocking water.

it have waterproof moistureproof  function.

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.
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:Ipad charging display does not support this accessory
Data line problem, it may be the data line to the bad, caused by poor contact. For the sake of the root
Q:What kind of KVM switch is this configuration below?
Hello according to your request can be used two sets of ordinary 16 cascade, to a control terminal control 32 hosts. Is the cheapest solution. According to my understanding of the domestic Haikang series of products cost-effective, you can understand the next.
Q:Fiber optic cable split box, integrated wiring box, cable terminal box, cable transfer box difference
KVV is the control cable, generally do industrial control; and RVS is twisted pair, generally used for weak system, to eliminate the interference requirements of the occasion, such as two-wire bus system, specifically, the electrical fire bus more Such as RS485 bus and so on.
Q:Wire and cable CCC product consistency is what
PVC line, the market is better with plastic, plastic, . Wantong, etc., if only home improvement, then the brand requirements do not need so high. Small brands are the same, we see the quality. Network cable, then preferred Ann or TCL.
Q:How to distinguish between power cables and electrical wiring on drawings
According to the control cable and the power of the different layers of laying, if the power cable to be multi-layer need to have 300mm spacing (or load capacity is large enough), if it is control cable, casually laying, if the laying of power cable laying below Layer, above the laying of control cable, but not too much affect the power cable cooling. If the high-voltage cable and low-voltage cable in principle do not allow common laying.
Q:Will the extension of the output of the electric vehicle charger wire affect the voltage?
National standard line, no problem. Do not pick up the heater in winter. If not the national standard line, that copper is not easy to go wrong, then use, from time to time touch the line is not hot, there is no problem.
Q:Seeking the basement of the outer wall piercing the cable after the casing, how to solve the water (200 points online)
Line width, and can not pass the gap between the chip pins, even after, but also because the distance between the wire and the lead is less than the electrical rules specified in the safe distance. In general, the ground can not pass through the gap between the chip pins, go outside or take the gap between the two columns through the gap. The width of the ground wire can also be set appropriately, and the wire is widened by adding a polygon brass cut. The safety distance in the electrical rules defaults to 10 mils, which is relatively small, and the safety distance of the different networks should be set separately as needed.
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
