It operates at above 33kv and overcomes the limitation of pin type insulator like the following.
In suspension insulator numbers of insulators are connected in series to form a string and the. Disc suspension insulator, fujian ruisen new materials co., ltd. Porcelain suspension insulator consists of one or more ceramic shells, metal end fittings, zinc sleeve. These types of insulators are available in two types namely connected cap type & interlinking/ hewlett type insulators.
Generally, it is made up of porcelain material that includes single or a string of insulating discs hanged over a tower.
Ball and socket, clevis and tongue, form disc insulator string. These are used for h.t. Insulator material, colour & type porcelain, glazed brown, disc 4. Specific technical parameters of tension & suspension disc insulator 1.
And whether porcelain suspension disc insulator is insulation tape, {2}, or {3}.
With the number of metalink links. A number of discs can be added to meet the demand of increased voltage of h.t. Suspension insulators or suspension strings are developed by attaching a number of closed insulators in series using metallic links. In suspension insulator, the conductor can be hanged under the support point.
It is only subjected to tension strength, but not bending moment and torque.
1, strong aging resistance 2, long service life 3, reasonable price Porcelain suspension insulator is designed to give unparalleled performance and reliability. Diameter of unit (mm) 255 i) suspension & single tension: It consists of a number of porcelain discs connected in series by metal links in the form of a string.
Salient features suspension insulators (porcelain discs) are the most widely used insulators for transmission & distribution lines.
From 40 kn, 45kn, 60kn, 70kn, 80kn, 100kn, 110kn, 120 kn, 125kn, 160kn, 210kn, 300kn upto 400kn. Iec 305 (bs 137 & as1137): 1 1 2 2 2 The porcelain insulator is used on substation & transmission line.
A wide variety of porcelain suspension disc insulator options are available to you, such as fiberglass, composite polymer.you can also choose from high voltage, porcelain suspension disc insulator,as well as from 10kv, {2}, and {3}.
Rated system voltage (kv) 132 220 400 2. A suspension type insulator protects an over headed transmission line like a conductor. A wide variety of disc suspension insulator options are available to you, such as porcelain, composite polymer and fiberglass.you can also choose from high voltage, low voltage and high temperature disc suspension insulator,as well as from 11kv, 220v, and 33kv. Porcelain disc insulator, with the most operating experiences, is widely used in high voltage transmission and distribution lines to hang or tension the conductor for its good performance of insulation property, mechanical property and chemical stability.
The suspension insulator consists mainly of two parts one is the cross arm and the other is the insulator which we also know as the disc insulator.
255 ii) quad & double tension: Is, iec, bs, ansi, australian specifications. U120b disc suspension insulator,disk insulator. This insulator is made of porcelain insulators, an iron cap, and fittings assembled by cement.
It helps to support and hand wire, insulation wires against tower.
The range of electro porcelain insulators offered includes pin insulators, post insulators, shackle insulators, suspension disc insulators, bushing insulators, guy strain insulators, solid core line post insulators and apparatus porcelain insulators.
