As Altınsoy Enerji, we design medium voltage disconnectors and insulators that form the foundation of reliability in power transmission and distribution infrastructures. Our products ensure the safe opening and closing of circuits in high-voltage lines and enable the system to operate in a stable manner. Each model we develop is optimized according to field conditions and customer requirements, and is manufactured with the goal of maximum performance and long service life.
The engineering-based quality approach applied throughout our production processes enhances both the safety and ease of maintenance of our products. The high-durability silicone materials used in our insulators provide superior protection against environmental effects, while our disconnectors ensure energy continuity with high mechanical strength and low maintenance requirements. For this reason, our products are preferred not only in local distribution networks, but also in power plants, industrial facilities and infrastructure projects.
At Altınsoy Enerji, we combine local manufacturing strength with international quality standards in every project. Our TEDAŞ-compliant MV disconnectors and silicone insulators deliver long service life and reliable performance. The solutions we develop through our engineering expertise increase the safety of power systems while minimizing operating costs. For us, every product is not just a piece of equipment, but a commitment of trust extending into the future.

Medium Voltage Disconnectors & Insulators
Outdoor-Type Medium Voltage (MV) Insulators
The outdoor-type medium voltage insulators manufactured by Altınsoy Enerji are developed to ensure safe insulation and uninterrupted system performance in power transmission and distribution lines. These insulators enable the safe separation of high-voltage lines and protection against environmental impacts. Designed for outdoor use, they operate reliably for many years even under harsh climatic conditions.
The advanced engineering approach and local manufacturing infrastructure applied in the production process increase durability while reducing maintenance requirements to a minimum. Each product is optimized according to field conditions and project requirements, showing high resistance to mechanical impacts, UV radiation, moisture, and contamination. Thus, both energy continuity and operational safety are guaranteed.
Altınsoy Enerji provides porcelain and silicone-insulated solutions for different requirements.
Porcelain insulators are ideal for heavy industrial applications thanks to their high mechanical strength.
Silicone insulators, with their lightweight structure and superior surface properties, deliver long service life in humid, dusty and corrosive atmospheres.
All our insulators are manufactured in compliance with TS EN 62271-102 standards and the requirements of the ISO 9001 Quality Management System. Our own brand, the POREL Series, is preferred in both the Turkish and international markets as a range of high-quality products. These products contribute to the goals of sustainability, safety and efficiency in energy infrastructures.

Indoor-Type Medium Voltage (MV) Insulators & Disconnectors
The indoor-type medium voltage disconnectors (sectionalizers) manufactured by Altınsoy Enerji are designed to provide safe insulation at high voltage levels and ensure uninterrupted system operation. These disconnectors are capable of opening and closing operations under no-load conditions and all poles are controlled through a common operating mechanism.
Each unit is optimized according to field conditions and project requirements, offering easy installation and maintenance advantages with its structure suitable for wall-mounted or vertical surface installation. They are produced in two main types: porcelain-insulated and silicone-insulated.
Indoor-type disconnectors provide safe electrical isolation between lines in power distribution centers, transformer rooms, circuit breakers and capacitor banks. These devices not only ensure safe isolation, but also increase the safety of maintenance operations.
All disconnectors manufactured by Altınsoy Enerji comply with the TS EN 62271-102 standard and the requirements of the ISO 9001 Quality Management System. Our in-house brand, the POREL Series disconnectors, are preferred in both the Turkish and international markets thanks to their high performance and long service life.

Load Break Switches
The load break switches manufactured by Altınsoy Enerji are reliable switching devices that can perform opening and closing operations under load in medium voltage systems. Thanks to the integrated arc-quenching system, electrical arcs that may occur during switching operations are safely suppressed, ensuring both operational safety and uninterrupted energy continuity.
Our load break switches are manufactured in four main configurations: Normal, With Earthing, Fused, and Fused with Earthing. They can be adapted to different operational requirements. Upon request, they can be designed as three-pole or single-pole, and suitable for vertical or horizontal mounting arrangements. According to user preference, production can be carried out with porcelain, epoxy, or silicone insulator options.
As a key component of power control in medium voltage networks, load break switches provide safe isolation in specific sections of power lines and enable controlled energy flow. They play a critical role in maintaining system safety, especially during maintenance, repair, or emergency operations. They are widely used in applications ranging from industrial facilities and power plants to urban infrastructures and distribution centers.
Altınsoy Enerji load break switches are manufactured with an engineering approach focused on durability and long service life. With their resistant structure against harsh environmental conditions, low maintenance requirements and high safety levels, they deliver continuous performance for many years. Each product is tested and approved in compliance with the TS EN 62271-103 standard and the requirements of the ISO 9001 Quality Management System.
As a result, load break switches are among the most reliable solutions for power control in energy systems. At Altınsoy Enerji, our goal is not only to deliver a product, but to provide the energy sector with safe, durable, and long-lasting solutions. Every load break switch we manufacture is an engineering product designed to ensure operational safety and energy continuity.
