gaom Underground cable, cable, and overhead power lines compared with the common, because it is often buried in the ground, so it is also called the underground cable. Cable conductor is wrapped by one or a plurality of mutually insulated insulation layer and protective layer made of wire, used to power or information from one place to another.After entering the modern society, the tense city land, traffic pressure, city construction and other reasons, the big city is widely used in underground cable transmission mode. Compared with the overhead lines, cable has the advantages of small footprint, transmission reliability, strong anti-interference ability etc.

gaom The Rated Voltage(kv):
1st class 0.6/1 1.8/3 3.6/6 6/10 8.7/15 12/20 18/30 21/35 kV, 2nd class 1/1 3/3 6/6 8.7/10 12/15 18/20 - 26/35 kV

4 core 25mm2 aluminium armoured cables are most suitable for direct burial or for installation on trays or ducts, Where there is a risk of mechanical damage, armoured cables should be used.

4 cores - red, yellow, blue and black
4. Formation
1) Single core
2) 2,3, or 4 cores - stranded together and the interstices may be filled with the sheathing compound or textile. A nonhygroscopic binder tape may be applied over the laid-up cores.
Black general purpose PVC compound
Single core - Aluminum wire
2,3, or 4 cores - Galvanized steel wire
Black general purpose PVC compound
gaom 1.Conductor
Plain, annealed electrolytic copper or Aluminum conductors, solid, circular stranded, or sectorial stranded, conforming to the applicable requirements of IEC
2. Insulation
PVC based thermoplastic or XLPE thermosetting material, conforming to the
applicable requirements of IEC 60502-1.
Insulated conductors are laid up, filled where necessary with non-hygroscopic material and covered with an extruded thickness of thermoplastic material.
4. Armour
Galvanized round wires, or flat strips, completely covering the assembly of cores
and a counter helix of galvanized steel tape on top; or two layers of steel tape,
complying to the applicable requirements of IEC 60502-1.
5. Sheath
PVC or PE based thermoplastic material, conforming to the applicable requirements of
IEC 60502-1.
gaom Conductor: Solid or Class B compressed concentric lay stranded 1350 aluminum meeting the requirements of ANSI/ICEA S-97-682.
Conductor Shield: Extruded semi-conducting thermosetting polymeric stress control layer.
Insulation: Extruded Ethylene Propylene Rubber (EPR) Class II and III as defined in ANSI/ICEA S-97-682.
Insulation Shield: Extruded semi-conducting thermosetting layer, clean and free stripping from insulation.
Copper Wire Shield: Helically applied annealed solid bare copper wires with a lapped non-metallic tape serving as a binder/separator.
Jacket: Black, non-conducting, sunlight-resistant (PVC) or LLDPE.
gaom 1. when the cable is only one single layer, the shielding layer equipotential at one end is connected with the ground.
2. when the cable has a double-layer insulation isolation, the outermost layer both ends of the shield ground connection, and the inner shield one end equipotential ground connection.
3. when the cable is used for the serious interference, rat frequently and lightning-proof, explosion-proof requirements, should adopt the armored shielded twisted pair cable. When in use, the armored layer both ends are grounded, the inner shield one end is grounded!

Over time, you may have learned which sunglasses frames work for your face. If you have a little head or close-set eyes, you might be avoiding wider-style frames so you don't look swallowed up. If you have a big head or high brow you may have more options, but you also need to be careful that you go wide and tall enough to actually give yourself enough periphery coverage. Then there's the trend toward oversized lenses in general that throws all those rules out the window! So how do you know what’s going to work for you in today’s modern world of shades? One place to start is to learn about your head shape. Use a photo app to draw an outline of your face on your phone to identify with one of the four typical shapes: oval, round, heart or square. Oval: Lucky ducks, you can wear almost any sunglasses styles and still look good. In general, go for frames that are equal to or wider than the broadest part of your face. And make sure shades cover your eyebrows and cheekbones. Round: Round faces tend to look especially youthful, so balance those soft features with more angular frames. Going smaller and squarer can also make round faces look longer. Or play up the youthful look with some fun and colorful sunnies. Heart: Think high brows and cheekbones, with a narrow chin. The distinguished heart-shaped face can handle frames that stretch a little wider than the forehead. Bold designs with heavier bottom accents also balance out that angular chin. Love. Square: Just like that round face, if your head is a square shape, you want to create balance with the opposite—something more oval. You can flaunt round and thin frames; semi-rimless styles that soften your jawline; or a model that goes wider than your cheekbones. While these are some pointers, with Jim Optical sunglasses you don't always have to play by the rules. Try variety of styles to see what makes you happy!
