Dimensions of studs for transformers. Input studs are brass, input studs are brass

A brass pin is one of the fastening elements. Most often it can be found both in the engineering and industrial sectors. They also serve to produce electrical communication between the winding down conductor and transformer buses with external power lines and power supply buses in circuits. Brass studs are the most durable and do not corrode.

Studs for power transformers made from various metals (as statistics show, these are mainly copper or brass LS59-1 according to existing GOST standards), in any diameter with thread pitch. The stud requires immediate replacement if defects and obvious damage appear on the thread when the stud burns out.

compound finished product there may be a fixing sleeve, or as it is also called a washer, that fixes the insulator. It is used on the types of transformer bushings produced by our plant. The main material for the manufacture of the fixing washer is aluminum grade D16T or D1T.

We draw your attention to the fact that if the phase or neutral studs of the transformer are replaced on the LV side, it is necessary to replace the oil and gas resistant gasket, which is located around the perimeter of the tank. A damaged pin must be replaced indoors; before doing this, the oil from the transformer must be drained to the marked level. With the stud, rubber seals, which include gaskets, bushings, seals and barrels, require replacement.

Qualified specialists of our company produce studs from various raw materials metals. Including brass of absolutely any diameter and with different thread pitches. The main specialization of our production is the production of studs for use in high-voltage transformers. And here only high-quality brass pins LS59-1 are needed in accordance with approved GOST standards. Our products have proven compliance with these standards.

You can also use additional service coating the finished part with tin-bismuth. This will extend the service life of the finished product and protect it from corrosion.

EnergoTrans LLC began production of Contact Clamps (Current Collectors, Flags) for transformers with a power of 400 kVA (M20x2.5 or 1.5 mm) from October 1, 2018 in a reduced size, redesigned form and best quality surface, which affects its cost to a lesser extent. At the same time, overall dimensions, provide the required cross-section of current-carrying sections and contact surfaces, eliminating overheating of the contact clamps.

EnergoTrans LLC began production of contact clamps (Current Collectors, Flags) for transformers with a capacity of 160 kVA (M12x1.75) and 250 kVA (M16x2.0) in reduced overall dimensions, which reflected a decrease in cost, from 07/01/2017. At the same time, the overall dimensions provide the required cross-section of current-carrying sections and contact surfaces, eliminating overheating of the contact clamps.

Since November 1, 2016, EnergoTrans LLC has mastered the production of HV and LV insulator heads (caps) of types 1, 2, 3 and 4 for transformers with a power from 25 to 630 kVA. This type insulating heads (caps) are made of cold steel grade 08ps, and have a galvanic coating "Zinc", and are offered in addition to the existing insulating heads (caps), made of brass grade L63. Steel insulator heads (caps) have a lower selling price, while their characteristics are not inferior to insulator heads (caps) made of brass.

Description

Brass input studs Energopribor can produce studs for any type of transformers (TM, TMG, TMZ, TMF, etc.) with a power from 25 to 2500 kVA. To order, you only need to indicate the diameter of the stud and the thread pitch To create an electrical connection for power cables or busbars electrical networks With taps or buses of power transformers, current-carrying rods (input studs) are used. The LV input stud set consists of two elements - a stud (current-carrying rod made of LS59-1 brass) and a fixing washer (a washer used to fix the IPTV insulator and made of D-16T aluminum). Input studs for HV and LV can be supplied assembled with a washer, or separately as components.
