Fittings and equipment used in power stations and transformers
Power substations, as the heart of the energy transmission and distribution network, require equipment that is at the highest standard level in terms of mechanical, electrical and safety. The smallest weakness in consumables and equipment can lead to widespread blackouts, damage to transformers, and even life risks. For this reason, the correct choice of substation fittings is considered a technical-vital decision.
What are electrical substation fittings?
Electric substation accessories include a set of metal and insulating parts that are used for installation, maintenance, connection and safety of electrical equipment in substations. These parts play the role of an interface between main equipment such as transformers, busbars, insulators and structures.
The most important fittings used in electrical substations
- Hot galvanized bolts and nuts
- Brackets and transformer support bases
- Copper and aluminum busbars
- Connection and branching clamps
- Tensioning fittings and bracing
- Earth connections and earth wells
- Polymer and stationary insulators
- Cable fasteners and holders Power
The role of fittings in transformer performance
Transformers are heavy and very sensitive. Using low-quality fittings causes:
- Destructive vibrations
- Increased energy loss
- Mechanical failure
- Decreased life of transformer
Products supplied by Klat Elektr are designed according to harsh environmental conditions (humidity, heat, dust).
Important standards of electrical substation fittings
- IEC
- IEEE
- National Standard of Iran
- Mechanical resistance test
- Corrosion and rust test

Why are substation fittings so important?
Power substations and transformers are the center of gravity of the energy transmission and distribution network. Any small defect in the mechanical and electrical fittings and equipment of this sector can cause widespread blackouts, damage to transformers, and even fatal accidents.
Therefore, the selection, supply and correct installation of electrical substation accessories is not just a simple purchase of equipment; Rather, it is a strategic and technical decision that has a direct effect on the useful life of the network and maintenance costs.
What are substation fittings and what is their role?
Power substation fittings are a set of metal parts, insulation and connections, which are used for:
- Installation and fixing of main equipment (trans, breaker, sectioner, busbars)
- Reliable transmission of electric current between components
- Insulation and separation of phases
- Mechanical and electrical protection
They are used. These parts may seem small and seemingly simple, but the failure of these small parts usually causes the most expensive and time-consuming outages.
The most important fittings and equipment used in electrical substations
1. Brackets and supporting structures
Brackets are responsible for maintaining heavy and sensitive equipment such as transformers, station insulators, panels and busbars.
Important features of power post brackets:
- Made of resistant steel with hot galvanized coating
- High mechanical resistance against static and dynamic load
- Resistance against corrosion, humidity and harsh environmental conditions
- Design according to the map and datasheet post
Klat Berq supplies all types of standard post and transformer brackets based on the project's needs.
2. Busbars and hard conductors
The busbars are the main path of current passing in the electric substations and are as follows:
- Copper busbar
- Aluminum busbar
- Tubular or flat busbar
are used. The selection of the cross section, material and installation type of the tires must be in accordance with the standards of rated current, short circuit current and temperature rise.
Accessories related to tires include:
- Bus clamps
- Bus holder
- Expansion joints
- Copper bolts and nuts or with suitable coating
They are all within the scope of supplying electricity.
3. Electric substation insulators and insulating equipment
Insulators are the key element of insulation between high pressure conductors and metal structures (earth). In the electrical substation, different types of insulators:
- Needle ballast
- Plate (suspended) ballast
- Stationary ballast
- High pressure polymer ballast
is used. Each insulator with fittings such as:
- Insulator clamp
- Pin and cap
- Hanging and tensile fittings
It will be completed. The quality of this set has a direct impact on voltage tolerance, surface pollution and the possibility of sparks and flashovers.
4. Connection fittings and clamps
All kinds of connection between bus-bus, bus-cable, cable-trans, etc. are made in the electrical substation. The most important of them:
- Screw clamps
- Press clamps
- Forked T-shaped clamps
- Bimetallic connections (aluminum-copper)
Incorrect selection of these parts can cause:
- Increasing the connection resistance
- Local heating
- Energy loss
- And finally burning the bus or cable.
Klat Electric works on providing high quality connections and current intensity standards to minimize these problems.
5. Galvanized bolts and nuts for electric post
Screws and nuts may be the simplest part of the fittings, but in the electrical substation you must:
- Made of resistant steel with hot galvanized coating
- With specific resistance class
- Resistant to vibration and mechanical shock
Be. Non-standard bolts and nuts cause loosening of connections and serious errors over time.
6. Earth system and earth connections
To protect the equipment and personnel, the electric earth post system includes:
- Earth bus
- Earth fasteners and clamps
- Earth belts and wires
- Welded and screw connections
This section is critical in terms of safety, and its connections must be resistant to corrosion and fault currents.
Challenges of choosing substation fittings in projects
There are usually several recurring challenges in implementation projects:
- The difference between the plan and the market stock
- There was no specialized supplier to provide the whole package of accessories
- The presence of nameless and non-standard products at a low price
- Delay in supply and creating project sleep
This is where having a professional supplier like Klat Berk, which focuses on network and substation fittings, is considered a competitive advantage.
The benefits of providing electrical substation equipment from electrical coils
- Centralized supply: Get all post and transformer fittings from one source
- Controlled quality: Cooperate with reliable suppliers and carry out quality control on the product
- Technical consultation: Suggest the right product based on the map, voltage and environmental conditions
- Nationwide distribution: Send orders to any part of the country with safe packaging Industrial

Power substation fittings and equipment and transformers are the backbone of the energy transmission and distribution network.
Although they seem to be minor, their failure imposes several times the cost of their purchase price.
By choosing a specialized supplier like Klat Elektr, you can:
- Risk of failure
- Unwanted shutdown
- and project rework
Minimize and ensure the long useful life of your equipment.
