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

The yellow wax tube is made of alkali - free glass fiber woven tube and coated with PVC resin and insulated by heating and plasticizing. PVC glass fiber paint tube has good dielectric and chemical resistance, as well as superior flexibility and flexibility.

Q:What is an insulated flame retardant electrical sleeve? Is it of good quality? Does it work to protect wires?

If the non GB, then I can not tell the amount, after all, he did not have a standard

Q:What are the specifications of PVC threading pipes?

Metal tube, ordinary carbon steel wire casing (wire tube), metal flexible pipe (galvanized pipe, stainless steel pipe, plastic coated metal snakeskin snakeskin tube)

Q:Silicone rubber sleeving can withstand high temperatures?

High temperature bending test at constant temperature of 260 DEG C of the heating furnace in 48 hours after the surface rupture or surface coating aging without stripping phenomenon generated at low temperature in the constant temperature heating test bending furnace in -70 C 1 hours after the surface rupture or coating surface without stripping. Film coating test after constant temperature furnace continuous testing, no surface peeling or dissolution phenomenon. Combustion test flame self extinguishing and no spontaneous combustion phenomenon (with UL "VW-1" and CSA "HFS" test) temperature test (2000hr) of 260 DEG C heating test normal 35 (30sec) 1200 C heating test of glass fiber intact flammability testing the burning speed of not less than 45s/25mm - SRG-1-7kv SRG-1-4kv (motor insulation can be achieved higher than H grade C) normal minimum insulation breakdown voltage of 7 kV / min 4 kV / min normal average insulation breakdown voltage of 10 kV / min 7 kV / min

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

Fiberglass tubes have been widely used in the fields of petroleum, power, chemical, papermaking, municipal water supply and drainage, plant wastewater treatment, desalination, gas transportation and so on, because of their unique advantages.

Q:LED fluorescent tube, with glass fiber board, or with aluminum substrate, okay?

Aluminum substrate is mainly good heat dissipation, whether the equipment life or use effect is good, high costGlass fiber fiber plate compared to the aluminum substrate, heat dissipation is too bad, cheap

Q:What are the materials used for the insulation breakdown of high voltage cables?

The yellow wax tube is a kind of glass fiber insulated tube, and it is coated with an alkali free glass fiber tube to modify the electric insulating tube made of polyvinyl chloride resin. It has excellent flexibility and elasticity, as well as good dielectric and chemical resistance. It is suitable for wiring, insulation and mechanical protection of motors, electrical appliances, instruments, radios and other devices.

Q:Insulated electrical sleeves will melt at high temperature

As long as the temperature reaches the melting temperature of the casing material, it will melt. Iron can be turned into liquid. Can polymer plastics not melt? It's just how much this "high temperature" means.

Q:What is a high temperature resistant insulated fire protection sleeve?

Characteristics and application:1. safety protection to protect the health of the workersAlkali free glass fiber itself has very strong tension characteristics, will not wrinkle broken, anti sulfuration, smokeless halogen-free non-toxic, pure oxygen combustion, good insulation, followed by organic silica gel after curing, strengthens its safety and environmental protection, effective protection of workers health, reduce the incidence of occupation disease. Unlike asbestos products, they are extremely hazardous to the human body and the environment.2. superior performanceThe organosilicon structure on the surface of the casing contains both organic groups and inorganic structures. This particular composition and molecular structure make it characteristic of organic compounds and inorganic compounds. Compared with other polymer materials, the most prominent is its high temperature resistance. The silicon oxygen bond (SiO) as the main chain structure, C-C bond is 82 thousand and 600 kcal / mole, SiO bond card / 121 thousand in silicon molar, so its high thermal stability, high temperature (or radiation) molecular bond doesn't break, do not break down. Silicone is not only resistant to high temperature and low temperature resistance, can be used in a wide temperature range. Both chemical properties and physical and mechanical properties vary little with temperature.

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).
