SIMOTEC Composite Long-Rod Insulators: A Result of Our Experience in Power Distribution, Especially
Know-How and Experience: To Meet Special Demands For around 150 years Siemens has been one of the leading electrical engineering companies. Today, the spectrum of supplies and services we offer in the fields of power generation and distribution ranges from composite insulators for switchgear and transmission lines to turnkey power plant projects. We set ourselves high standards and also the customers benefit from our know-how: SIMOTEC® insulators are now available as long-rod composite insulators.

Tried and Tested: SIMOTEC Insulators for Overhead Transmission Line Construction
Customized Insulators of Typical Siemens Quality: For Complete Satisfaction
Numerous tests have demonstrated the enhanced safety and reliability (even in the presence of ozone and UV radiation, at extreme temperatures, and when exposed to high mechanical loadings in the event of storms or icing. The extraordinarily high resistance to fracture makes them immune to vandalism. This means there is no interruption in electrical power supply and thus no loss of income.
With a standardized range of fiber-reinforced epoxy rods of different lengths and variable shapes for silicone shielding, we are able to provide optimized individual solutions as quickly as possible – for any size of transmission line and any type of mast design. We keep strictly to deadlines and offer short delivery periods.
Furthermore, the low weight and high inherent stability of SIMOTEC composite insulators reduce the effort associated with the construction of towers. Foundations, transport and erection also involve far less expenditure and this considerably reduces system costs.
And the more demanding and complex your requirements are, the more you benefit from our expertise in all aspects of power generation and distribution. We channel this expertise and ingenuity into our comprehensive consultancy package.
Moreover, SIMOTEC composite insulators save on costs associated with maintenance and cleaning. Air pollution, acid rain and sea salt have no effect on the insulating properties of the silicone.

per shed + 60 mm (2.36 inch) creepage distance
Arcing distance
Creepage distance: 2.5 x arcing distance ≈
Creepage distance: 3.6 x arcing distance ≈
Flexible Choice of Creepage Distance with SC and HC Shed Profiles Thanks to the hydrophobic properties of the silicone SIMOTEC composite insulators also exhibit superior electrical performance when exposed to heavy contamination. With an SC or HC shed profile they satisfy the stringent requirements of the creepage distance classes specified in IEC 815. The desired creepage distance can be fixed individually by the number of small sheds used. Each shed increases or reduces the creepage distance by 60 mm (2.36 inch). The creepage distance of an insulator with an arcing distance of 1000 mm (39.37 inch) and SC profile can be as much as 2500 mm (98.43 inch), and with an HC profile as much as 3600 mm (141.73 inch).
With an SC profile the creepage distance is equivalent to two-and-half times the arcing distance.Each small shed increases/reduces the creepage distance by 60 mm (2.36 inch).

SIMOTEC Long-Rod Insulators: A Long Service Life and High Operating Reliability
Epoxy rod

low-stress shrink-fitting process which avoids any damage to the rod interior. Carefully optimized process parameters and uncompromising quality assurance guarantee an extraordinarily long service life and reliable operating performance under all field conditions. The most meticulous selection of components and state-of-the-art fabrication are also used when applying the outer silicone shielding. A primer ensures a permanent chemical bond between the rod, fittings and silicone. Prior to the casting process it is sprayed onto the rods with the aid of computer control. The silicone is then applied in one cast. It directly seals the rod and the joint with the fittings. Neither moisture nor other extraneous matter can therefore penetrate. Crevice corrosion which

Crevice corrosion which could damage the joint between rod and fitting is ruled out.
A primer ensures the permanent chemical bond between rod, fittings and the silicone which perfectly seals and envelopes the joint.

The design of the corona rings was optimized by means of computer simulation of the electrostatic fields. No extreme field increase therefore occurs at the joint between the silicone and fittings. Up to a voltage of around 170 kV SIMOTEC insulators do not require corona rings. For higher voltages we offer customized versions.
