Silk covered wire 1

Silk covered wire refers to the conductor or enameled twisted wire around the outside package silk or filaments (nylon, polyester, silk, the sticky silk, etc.) made of insulation and electromagnetic wire.

type

Polyester silk covered wire

Using polyester polyester as electromagnetic silk-covered wire winding package material. The biggest characteristic of polyester silk covered wire is straight weld. In use without sand, can be directly welding, to avoid the caused by uneven sand head and virtual welding, improve the welding quality. Its insulation performance, high frequency performance, heat resistance, etc., is a natural silk silk covered wire high. The product after many tests, the Q value and the inductance L were higher than or equivalent to the same kind in a polyester silk covered wire. Polyester yarn is a kind of chemical fiber products, it is rich in resources, and the price is 70% lower than the natural silk, polyester silk covered wire is a kind of very promising electromagnetic wire products.

Glass silk covered wire

With alkyd resin paint dipping non-alkali fiberglass winding and round copper wire, flat copper wire made of a glass silk covered wire can be used in motor, electrical appliance in the winding. Double glass glass silk covered wire in any of the following types: SBEC baoyuan copper wire, SBECB double glass BaoBian copper wire, QQSBC: single glass package baoyuan acetal paint line, the high strength QZSBC: single glass package baoyuan high-strength polyester paint line.

The above four models of silk covered wire, QQSBC working temperature of 125 ℃ respectively, QZSBC working temperature is 135 ℃, SBEC and SBECB working temperature is 150 ℃. [2]

Characteristics and application

Silk covered wire relatively bare wire, increase the dielectric strength, reduce the surface temperature, increase the value of "Q", silk covered wire and has the same characteristics of enameled wire. More used in antenna inductance, high power lighting system, video equipment, ultrasound equipment, high-frequency inductors and transformers, etc.

Enameled wire

With the insulation of the cladding wire electrical insulating varnish. Bare copper wire dipping varnish after baking. Used for winding transformer or motor coil. By insulating varnish is divided into different acetal enamelled wire, polyester, epoxy, polyurethane, enameled wire enameled wire, oily enameled wire, etc. Acetal enamelled wire high mechanical strength, oil resistance and good sealing. Oily enameled wire heat resistant performance is good, used to make more relay coil and voice coil; Good frequency characteristic polyurethane enamelled wire, is easy to be infected with the color, also can be directly (not to paint layer) welding, widely used. Heat resistance performance of all kinds of enameled wire, depends on the insulating paint, general is 373 ~ 403 k, and heat resistance of 473 k.

Cotton covered

Insulation wire of cotton yarn. By the bare wire enameled wire bound up a layer or cotton yarn on the second floor. Can be 368 k of heat-resistant, after immersion treatment can also improve, not easy to damage the insulation layer, commonly used in high frequency choke and medium wave magnetic antenna coil (with multiple strands of cotton covered).

Shielding wire

On with insulating clad wire woven wire mesh wire. Sometimes on the outside of the wire mesh and apply a layer of insulating material. In use, and the wire mesh or casing connections, can for shielding electromagnetic radiation and external electromagnetic interference. Commonly used in electronic equipment, high frequency circuit and other circuit shielded cables
