Durostone® Lead through boards

Product catalog summary

Overview: The document provides technical specifications and applications for Durostone® lead-through boards, which are used in the industrial furnaces transformer industry as an alternative to aluminum and hardpaper boards. These boards are primarily used for electrical insulation of copper conductors and surface sealing.

Specifications:

Material: Glass fibre reinforced plastic.
Properties: Excellent electrical insulation, high-temperature stability, and high mechanical strength.
Maximum Dimensions: Durostone® EPC 205: 4,200 x 3,400 mm; Durostone® UPM S2: 2,400 x 1,200 mm.

Technical Values:

Electrical Properties: Surface resistivity, breakdown voltage, and electric strength at 90°C.
Thermal Properties: Thermal conductivity, temperature index, and coefficient of linear expansion.
Mechanical Properties: Bending strength, impact strength, tensile strength, and compressive strength.

Remarks: The document notes that the provided data are average values and not guaranteed. Variations may occur within a 50 mm area, and tolerances are according to EN 60893-3-5 standards.

Applications: Durostone® boards are used in transformer building due to their proven performance in electrical insulation and mechanical stability. They can be economically produced in large dimensions using CNC milling machines and are coated with heat-resistant insulating varnishes.
