5 Types Of Electric Wire You Should Know
To know us more, please visit ￫ ￫ www.spider.com.tw
●PVC wire and Copper conductor Wires
The main features of products: pure metal
conductor, insulation and sheath, such as steel core aluminum stranded wire,
copper bus, electric locomotive line; processing technology is the pressure
processing, such as melting, rolling, drawing, stranding / pressing twist;
products are mainly used in suburban and rural areas, users the main line,
switch cabinet etc..
●Power cable
The main features of the products are:
crowded outside the conductor (around) insulation layer, such as overhead
insulated cables, or a few cores (corresponding to the power system phase, the
zero line and the ground), such as more than two core overhead insulated
cables, or increases the jacket layer, such as plastic / rubber sheathed cable.
The main technology has drawn, stranded, insulated out (wrapped), a cable,
armored, protection layer extrusion, different process combination of various
products have certain difference.
● Electrical equipment with wire and cable
● Communication cables and optical fiber
(brief introduction)
●Electromagnetic wire (winding wire)
Mainly used for all kinds of motor,
instrument and meter, etc..
Selection The Best Lighting Cable
● Check the appearance. Qualified products
of its insulation (sheath) layer of soft, flexible and flexible electric cable,
the surface layer is tight, smooth, no rough sense, and have a pure gloss.
●The surface of the insulation pvc wires
and cables(sheath) should be clear and resistant to wear. Non regular
insulation material production, insulation layer feel transparent, brittle, no
toughness.
● Check the insulation layer. National
standard for wire insulation layer uniformity of the most thin point, the
average thickness of a clear data. The insulation layer of the normal electric
wire is uniform, not the core, and is tightly packed in the conductor.
●Check the certificate. Standard
certificate of products should be marked with the name of the manufacturer,
address, after sales service telephone, model, specifications and structure,
the nominal section (that is, the usual 2.5 square, 4 square wire, etc.)
