Q:What's the use of a wax pipe in an electrician?

Insulation, yellow wax tube is generally used in equipment, need to strengthen the insulation place, as well as the role of flame retardant, prevention and control of electric wire leakage due to high temperature

Q:The use of soft glass fiber insulation casing line please do

Polypropylene is acrylic, polyester is polyester. It's not good to make quilts! If you must choose chemical fiber, hollow cotton to the good;

Q:The main features of glass fiber tubes

1, good corrosion resistance. The composition of main raw materials of glass fiber reinforced polymer composition used in unsaturated polyester resin and glass fiber, can effectively resist the corrosion of acid, alkali, salt and other medium and untreated sewage, soil corrosion, chemical wastewater and many chemical liquid erosion, in general, to maintain safe operation for a long time.2, anti-aging and good heat resistance. Glass fiber tubes can be used for a long time in the temperature range from -40 to 70 degrees Celsius, and adopt special formula of high temperature resistant resin, and can work at normal temperature above 200 degrees celsius.3, good frost resistance. Minus 20 degrees below freezing in tube will not happen after cracking.4, light weight, high strength. The relative density is between 1.5~2.0 and only 1/4~1/5 of carbon steel, but the tensile strength is close to or even higher than that of carbon steel, while the specific strength can be compared with that of advanced alloy steel. As a result, aviation, rockets, aerospace vehicles, high pressure vessels, and other applications that need to reduce weight have excellent results.5. Good design. Can flexibly design a variety of structural products to meet the use of requirements, you can make the product has a good integrity.

Q:What's the wax pipe?

Polyvinyl chloride fibre glass hose (Huang Laguan): English name is "PVC SILICONE FIBERGLASS SLEEVING"". This product is woven from E-glass fiber and coated with polyethylene resin. The utility model has good flexibility, elasticity, insulation and chemical resistance, and is suitable for wiring, insulation and mechanical protection of electric machines, electric appliances, instruments, radios, etc..

Q:How many kinds of electric threading pipe are there?

Ceramic tubes1 、 threading porcelain bushing2 、 glass fiber braided insulating sleeve

Q:PE what do you mean by "PE" in plastic pipes?

The molecule of polyethylene is a long chain structure or a branched structure, which is a typical crystalline polymer. In the solid state, the crystalline part coexists with the amorphous. The crystallinity depends on the processing conditions and the original treatment conditions. In general, the higher the density, the greater the crystallinity. L.DP E crystallinity is usually 55% - crystallinity of HDPF 65%, 80%-90%.

Q:What are fiberglass tubes, and what are they mainly used for?

The forming process of the glass fiber tube is that the glass fiber wire is impregnated with resin and solidified in a high speed polymerization device with light and electricity, and is pulled, pulled and extruded. Because of the different kinds of resins used, they are called polyester glass fiber reinforced plastics, epoxy glass fiber reinforced plastics and phenolic resin glass fiber reinforced plastics. It has the characteristics of light and hard, non conductive, high mechanical strength, anti-aging, high temperature resistance, corrosion resistance and so on.

Q:Insulated electrical sleeves will melt at high temperature

Insulated electrical sleeves are divided into several materials, such as fiberglass insulated sleeves, PVC bushings, heat shrinkable sleeves, etc.. The temperature characteristics are different, such as the applicable temperature range of the heat shrinkable sleeve: -55 DEG C to 125 DEG C.

Q:What are the transformer bushings?

Oil immersed transformer bushings are generally ceramic, in order to stability of the ceramic bar. I said the plastic, it is estimated that you say BMC, SMC, DMC resin bar! These new things are generally seen in some dry-type transformers, bushings (insulators), busbars, insulators and general switches, bushings, and some through wall bushings. Oil immersed transformers are estimated to be afraid of their physical and chemical changes during long periods of oil immersion.

Q:Where is the best ceramic fiber packing?

Compared with asbestos textiles, ceramic fiber textiles have the following advantages:1) the continuous use temperature can reach 1000 DEG C, and the service temperature can reach 1260 DEG C for a short time.2) has good acid and alkali corrosion resistance and aluminum, zinc and other molten metal melting ability.3) good high temperature strength and heat insulation performance (refer to physical and chemical indexes).
