A stringing block is used to give good support and let the movement of a cable which is installed. These are usually used overhead but there are also particular designs used at the entry to a conduit system. Stringing Blocks are built of good aluminum alloy, which makes them very lightweight, robust, and durable. The sheaves stop damage to the conductor and the anti-friction bearings packed with aviation grease make these blocks hardy to risky conditions. We have developed a whole range of Stringing Blocks which includes standard, removable, tandem Stringing Blocks. Besides this traditional range, numerous special solutions have been calculated to overtake problems and difficulties faced by many projects in dangerous conditions. For a new generation of conductors, an advanced range of stringing blocks has been developed. To safeguard the top safety level on job sites the foundation devices available for all the Stringing Blocks and turning array blocks models are designed.
The rugged stringing blocks for adss wire feature high strength and low weight at a very valuable price. With a load limit, they can be arranged with five different mounting options. Enduringly lubricated bearings deliver long-term durability and an exciting temperature operating range. The configuration is
- 13.0-lbs depending on the configuration
- 7” Block bottomless groove ball bearings
- 3” Sheave rim width and enduringly lubricated to withstand 250F
- Machined groove for concentricity
- This is cast from A356 Aluminum and also heat treated
- Industry-standard locking latch
- 2″ diameter of the conductor and Universal Stringing Block Cut Sheet
Features of the Stringing blocks:
- This is 2,500-lb overhead SWL
- This is Double shielded with a groove bearing
- This is permanently lubricated to endure 250F
- It has a profile machined groove for concentricity
- This is a UB1 Series Block with a ball hook
Specifications of Stringing blocks:
- It has a 7” Block O.D.
- It has a 3” Sheave rim width
- It has a 3-1/8” Width throat
The stringing blocks for adss wire prove what can happen to rollers and cables during the angled stringing and the Universal Stringing Block proves what can occur to cables during angled stringing. The cable will be caught between the sheave and frame, which causes binding, overstressing on the block, and damage to the conductor. A good quality Stringing Roller removes all these problems as it lets the line properly position the situation, thereby saving lost and expensive time consumed moving the angle settings. These string blocks are the fast and most effective roller available. There are many different models of the stringing blocks, varying in mass and stringing capacity.
Properties of Stringing blocks
The Stringing Block is a lightweight, but exceptionally rough, and reliable distribution stringing block. Combined with its associated hardware and its accessories, it also affords values and contractors excellent versatility in how and where it is deployed and also in the range of connection problems it can help to solve. Its very low-friction bearings reduce high block efficiency, which helps to make the most of stringing distances while minimalizing pulling tensions and reducing the loads on stringing equipment. The stringing blocks for adss wire are lightweight and the durability is derived from the materials and approaches used to make it. The substance used for the frame is virgin aluminium, which is an aluminium alloy with a very tight controlled proportion of materials to promise the best performance during manufacture and also in the field. Virgin aluminium material is material that has not been assorted with any scrap material, not even with a scrap of what may have once been a similar alloy. The fact that we use virgin material promises that the material is precisely and only the pure and right alloy, and that it has not been polluted by impurities like iron that often escort non-virgin material. The frames are molded as molten metal. The properties and cleanliness of the Aluminum assure that the molten metal flows easily and evenly throughout the mould, guaranteeing proper and even density through the finished frame. Good density and consistency combined with the cleanliness and metallic properties of the alloy promise that the frame is strong but trivial, and assure that there are no interior voids or fragility that could cause the sudden whole failure of the block in the ground. The sheave is an enduring mould casting that is heat-treated for long life for numerous applications of conductor stringing and for cable placement. The sheave has sealed ball bearings greased for life under usual conditions. This will deliver a constant efficiency during stringing to decrease the amount of force throughout the pulling and tensioning processes.
The Fittings which can be used:
Fittings are the hardware add-ons that fit into the socket connection at the top of the stringing blocks in order to hang the blocks from fittings like hooks, lines, and brackets. You can see how your blocks with fittings can be used if the blocks will be suspended or hung either immediately or in the forthcoming and it has features like
- High strength with low weight
- 2,500 lb. supreme working load
- Positive fastening handle with a safe spring-loaded latch and large pull-loop on the side assembly for relaxed conductor clip-in and hot-stick processes
- It has High-efficiency and a low-friction
- It has a special rope groove to suit bare or insulated cables
- It has a High-strength and lightweight construction for relaxed handling
- All the blocks are fitted with a high-capacity bush and beckets
- The Identification labels show volumes and other relevant facts
Other details and features are
- It has Specialized Sheaves with a ball or roller bearing
- It is designed with special grooves to suit all the conductors
- It has a Special surface finish like Special coatings, Zinc plated, and Galvanizing.
- It is manufactured in stainless steel, as a corrosion shield
- Special stringing blocks can be factory-made to suit any application.
Applications of stringing blocks
It is used for bundled conductors stringing and all the sheaves are made of good quality nylon, the chief sheave is made in steel, particularly designed with high strength.
