Company Overview
NIKDIM Ltd., located in Kazanlak, Bulgaria, is a prominent manufacturer of low and medium voltage electrical apparatus since 1991. The company employs around 200 skilled personnel and operates certified quality management systems (ISO 9001:2000). It produces a broad range of electrical products including medium voltage fuses, fuse holders, NH fuses and bases, screw type low voltage fuses, disconnecting switches, lever breakers, porcelain insulators, and custom electrical porcelain appliances. NIKDIM serves Bulgaria's electric power system and exports over 40% of its production internationally.
Product Range
- Medium Voltage Fuses: Rated for 6.3 kV to 35 kV, including Series I-IV with varying pin strike forces and breaking capacities.
- Fuse Holders and Bases: Indoor and outdoor types compliant with IEC and BDS standards, some with integrated arresters.
- NH Fuses and Bases: Low voltage high power fuses (sizes 000 to 4), rated up to 1250 A, with detailed electrical and mechanical specifications.
- Screw Type Low Voltage Fuses: Types DII E27 and DIII E33, rated 500 V with 50 kA breaking capacity.
- Disconnecting Switches: Types RM, ROM, ROS for 10 kV to 35 kV networks, available in indoor/outdoor mounting, manual operation, with safety blocking features.
- Lever Breakers and Switches: Manual devices rated up to 1000 V and 1000 A.
- Porcelain and Epoxy Insulators: Wide range for low and medium voltage applications, including bushing, carrying, and support insulators compliant with BDS, IEC, and DIN standards.
- Custom Electrical Porcelain Appliances: Manufactured by pressing or shaping, including special purpose and steatite appliances for industrial and military use.
Technical Specifications
Medium voltage fuse links are designed per IEC 282-1 with rated currents from 2 A to 160 A and breaking capacities up to 60 kA. Series I and II are for normal pin strike (20 N), Series III for higher pin strikes (50-120 N), and Series IV for 24 kV applications. High voltage fuses for measuring transformers cover voltages up to 36 kV with rated currents of 2 A.
Fuse bases and holders meet IEC 282-1 and BDS standards, designed for specific voltage ratings and mounting conditions. NH fuse links and bases comply with BDS EN 60269-1:2002, with detailed power loss and resistance data. Screw cap fuses conform to BDS ND 630.31 S2:2002.
Disconnecting switches cover rated voltages of 10 kV, 20 kV, and 35 kV with rated currents up to 1250 A. They include indoor porcelain-insulated types and outdoor vertical/horizontal mounting variants, some equipped with arc chambers and stainless steel components for harsh environments. Manual operation is via RLZ series drives with safety blocking mechanisms.
Standards and Quality Assurance
- Compliance with IEC 282-1, BDS 8945-79, BDS EN 60269-1:2002, BDS EN 60129+A1+A2, BDS ND 630.31 S2:2002, DIN 40680, DIN 41580, and other relevant standards.
- Materials include porcelain type C-110, epoxy, copper and brass contacts with nickel plating, and stainless steel for corrosion resistance.
- Quality management certified under ISO 9001:2000.
Installation and Operational Recommendations
- Select fuses matching rated current, voltage, and breaking capacity requirements.
- Install fuse bases and holders according to indoor or outdoor specifications to ensure safety and performance.
- Disconnecting switches are intended for no-load switching; manual operation and blocking devices are critical for safe use.
- Consider environmental factors such as temperature (-10°C to +60°C), humidity (60% at 40°C), and altitude (up to 1000 m) during installation.
- Custom fuse designs and special purpose porcelain appliances are available to meet specific customer needs.
Additional Product Details
- Bushing Insulators: PRB and PRBO series for 10 kV and 20 kV substations with rated currents 200-1000 A, tested for variable frequency and impulse voltages.
- Medium Voltage Carrying Insulators: Type VHD for overhead lines up to 25 kV, with mechanical and electrical test data.
- Rill Insulators: For electrical panels up to 1000 V, with detailed dimensions and weights.
- Epoxy Insulators: Cylindrical and conical types rated for 10 kV and 20 kV, suitable for high voltage fuse applications.
- Isolating Bodies for NH Fuses: Porcelain bodies compliant with BDS and DIN standards.
- Ceramic Bodies for Chemical Industry: Designed for filling applications with strict dimensional tolerances.
- Installation Electroporcelain Appliances: Manufactured by half-dry pressing method per BDS and DIN standards.
- Special Purpose Appliances: Made from electro-porcelain and steatite for radio-electronic and military industries.
- Material Properties: Low water permeability (≤1.5%), high density (≥2.2 g/cm³), strong mechanical properties (bending strength ≥30 MPa), high electrical resistivity, and thermal stability.
New Developments
- Power disconnecting switches for horizontal outdoor mounting with remote control for line sectioning.
- Rotary-type disconnecting switches for indoor mounting, designed for transformer substation integration.
