Reinforcement towing


Earrings (lugs)

Earrings(lugs) such as CP and CDS designed to produce insulated wire suspension rope(hangers) and lightning protection of overhead transmission lines.
Earrings must be connected in a pestle with a cap insulator or ear (lug). The dimensions of nests insulator caps ditch and ears(lugs) must comply with the conditional size of pistils earrings(lugs) (GOST 27396-93).
Earrings oneclawed (onearm) (valved) junction socket lug (hole)  eye must be connected to the steel  reinforcement, which has doubleclawed (valved) GOST 11359-75 (lug). Breaking load earrings to match the breaking load of the connected with it towing fixture.
The choice of earrings for the acquisition of cable insulation hangers and fixtures overhead line electricity transmission made depending on the type of facility or abalone.




Ears (lugs)

Ears(lugs) are designed to connect the rod suspension (hangers) insulator, or other linear earrings (lugging) with steel reinforcement (fixtures). Spherical socket swivel lugs in accordance with GOST 27396-93 is performed. The coupled time action (dimensions) lugs must comply with the requirements of GOST 11359-75. Eyelets (junction socket hole (lug)) for air overhead line of electricity transmission give issued the following types:

U – ears (lugs) shortened
U1 – oneclawed (onearme) (valved) (junction socket (hole) lug) ears;
U1K –oneclawed (valved) (junction socket (hole) lug)  ears cropped;
U2 – doubledclawed (valved) (junction socket (hole) lug) ears;
U2k – doubledclawed (valved) (junction socket (hole) lug) ears cropped;
US - ears (lugs)with a special curved finger (pin);
USC - ears shortened with a special bent finger (pin).

 For locking the rod bushing and pestle in a nest earrings ears (lugs) supplied with W-shaped locks.




Mounts (fastening hubs)

Mounts (fastening hubs) types of KGP, KG, KGT, and KGN are designed for mounting tension and supporting insulating suspensions(hangers) to the supports of overhead transmission lines and distribution systems. Mountings of the type quark-gluon plasma to support the insulation hangers have a mechanical strength that the failure load(ensures indicating destructive) at specified angles of deflection of insulating suspensions(hangers) of up to 45 graphs (degrees) both along and transverse to the axis of the transmission line traverses.

The mount is designed for grades KGP-9/12-3 mounting tension insulating suspension destroyed depleting(failure) load of 90 kN (9 ton) for deflection angles up to 30 degrees in the plane of the U-bolt and 20 degrees in the plane perpendicular to it. In the mode of fastening the supporting insulating suspension(hanger) mount failure (destructive)load is 120 kN (12 ton).

Mountings of the type quark-gluon plasma have dimensions corresponding to the size of the unified fastened intermediate supports(pylons).

Mounts such as KG is a stronger version of mounting tension and supporting insulation hangers. They are designed for a range of destructive loads from 120 to 400 kN and ensures reliability when operating in dynamic and fluctuating horizontal and vertical GOVERNMENTAL loads.

In the attachment sites of the type CG after tightening bolts U-bolts, nuts, recorded(fixed) from self unscrewing(punching).
The mount stamps KGT-7-1 is designed to support the suspension mount lightning protection cables to wooden supports(pylons).

Mounts isolating suspension type REAG used on special transitions with large mechanical loads and allow to bind to the supports, and other tubular structures. Mounts are mounted on a support between the two parallel kerchiefs.

Braces

Braces are designed to go with the swivel chain connection on the connection type of "finger-lugs", change the location of the axis of hinge, coupling fittings, designed for different loads.
Brackets are available in three types:

• SK, SKD - hinge bracket with a chain;
• SKT - staples threeclawed (threearm) flat.

Staples types of SK and SKD have on the one hand doubleclawed GOST 11359-75 eyelet, on the other hand ¬ HN provide a swivel chain connection to the same standard. Staples such as SK can make the transition from the shackles of a number of loads on adjacent brackets (pain Sheha(large) or smaller) number of loads through the chain link. Staples such as extended access control have increased building height. Their use in isolating suspension(hangers) is recommended only in exceptional cases where the staples of normal length, for any reason not to apply.

Staples such as SKT threeclawed type have on the one hand oneclawed(onearme) eyelet with a compound according to GOST 11359-75, and on the other hand doubleclawed(doubledarme) eyelet on the same standard.




Links intermediates

Links intermediates intermediates are intended to increase and regulate the length of the suspension(hangers), the transition from one type of connection to another, change the location of the axis of hinge, coupling fittings, designed for different load Noah.

Intermediate links allow you to implement:
• extension of insulating suspensions (hangers) (units types PR, 2PR, PRT);
• changes in the plane of the hinge (such as PRV, links);
• adjustment of the radial type rocker 3KL, 5KL, 8KL (links 2PRR type);
• Ease of installation (units of type PTM);
• transition compounds with different reinforcement failure load (units of transitional type of PRT, PRS);
• the transition from the compound "finger-eye" to the chain compound (such as PRC units).




Rocker

Rocker arm assembly used in the double circuit or multichain(multicircuit) insulation hangers to ensure uniform distribution of load between the individual chains of insulators by means of articulation. Beam is also used for joining the single circuit isolating suspensions of two, three or more phase conductors.

Structurally, the rocker performed universal, and oneribed(, doubleribed. However, they can be double circuit, three circuit, three-prong, a four, five-way, eight, balance and special. Two edge rockers of all versions are equipped with a threaded end of the fingers, nuts and holders (latches).

The special type of rocker rocker are KL.

Rocker type KL used for the union of all chains of insulators after the installation and ensure reliable operation ting line at one chain is broken in two and isolating three circuit suspension, one or even two chains of insulators - in four and five circuit suspension, preventing the fall of the wire to the ground.

Rockers are set to stretch isolating suspension with separate attachment to the support of two, three, four, five and eight wires of the split phase. The rays of the beam are attached to the fingers(pins) of the intermediate links of variable types and PRR, 2PRR.
