MICC Enhanced Grade Wiring Cable Seals and Insulators
A seal is normally required at each end of a MICC Cable to provide a means of electrical connection. The Standard Brass 105°C Seal is suitable for the majority of general wiring applications. However since MICC Cables are used in a wide variety of environments, a comprehensive range of seals and insulators are available to suit every need.
A complete termination comprises a seal to provide a means of electrical connection and a gland to secure the cable into the appropriate apparatus. Externally threaded brass compression glands are available with ISO metric threads as standard with other thread forms available on request. Internally threaded 20mm ISO metric brass compression glands are available for the full range of 2, 3 and 4 conductor, 500 volt light duty cables.
Standard Seal
Continuous operating temperature range of 80°C to 105°C. These standard seals are suitable for all general wiring applications. Available in plain or earth tail. Use RMX compound.
High Temperature Glazed Insulator
For environments up to 250°C, a glazed insulator can be constructed as follows:
- Use the brass screw on pot from a standard seal (ref RPS).
- A cap or disc is not required.
- Use PTFE conductor sleeving (Ref RZPT) instead of the PVC Sleeving.
Please note that this insulator may not maintain a high insulation resistance (IR) at ambient temperatures. Use RMG Glazing Flux.
Fire Resistant Seal
When fire resistance is required, a standard 105°C seal Ref. RPS may be used provided that the standard PVC sleeving is replaced by silicon elastomer coated glass braided sleeving Ref. RZPS. Such seals will pass a circuit integrity test, essentially as given in BS 6387 for Category C, with seals in a 950°C flame for 3 hours. Use this seal when radiation resistance is required, as it has been satisfactorily tested to 100 M Rad. Use RMX Compound.
