Our Facility

Welcome to our facility. Built specifically for ELTEK Labs, our 2,000 square meters structure was designed to our exacting specifications. With four distinct laboratories under one roof – as well as the world’s largest thermal aging capability – ELTEK is the lab of choice for hundreds of companies from around the world.

The Component Compatibility Lab tests to various standards including – but not limited to – Sealed Tube Chemical Compatibility Testing (ASTM D-5642 / UL 1446) and Compatibility of Construction Materials with Insulating Oil (ASTM D-3455). Our testing allows Electrical System manufacturers to make material changes to already existing systems without the need of full thermal aging.

The Material Properties Lab has the capability to perform over 300 tests on a wide variety of Electrical Insulation Materials (EIM). Common tests run to ASTM standards are Inclined Plane Time-to-Track (ASTM D-2303); Comparative Tracking Index (ASTM D-3638); Dust Fog Tracking and Erosion (ASTM D-2132); Dissipation Factor and Capacitance (ASTM D-150); High Voltage-Low Current-Dry Arc Resistance (ASTM D-495); Surface Volume Resistivity (ASTM D257) and Hot-Wire Ignition (ASTM D-3874). Also performed in this lab are several tests to UL standards such as High Current Arc Ignition (UL 746-A); Glow-Wire Ignitability and Flame Test (UL 746-A / IEC 60695) and Test for Flammability of Plastic Materials (UL 94).

LTTA / RTI is a method of establishing a thermal rating for a "candidate" material by comparing it to a “control” material which has an established rating. Specimens undergo thermal aging and are then tested and a rating is established based on a comparison between the candidate’s results and that of the control’s. Pictured is the Phenix High Voltage (150,000 volt) Dielectric Tester.

The Electrical Insulation Systems Lab (EIS) offers clients the ability to evaluate two or more materials (a minimum of one EIM and one conductor) in a single test specimen. The inclusion of materials into a single test specimen, or General Purpose Model (GPM), allows for the evaluation of interactions that may occur between the materials that cannot be evaluated when traditional EIM level testing is conducted. In the EIS Lab we routinely run systems programs using IEEE-117 (low voltage); IEEE-275 (high voltage); IEEE-429 (high voltage / submersible); IEEE-259 (low voltage / transformers) and IEEE-C (high voltage / transformers).
