Hazardous Areas
Fire Rated Enclosures
Standard Fire RatingsAvailable on Abtech Stainless and GRP rangesIEC331 Fire Test• 750°C for 3 hours followed by visual inspection• Then 5kV insulation resistance testBS6387 Fire Test - 3 separate tests1. Fire alone: Category C
• Flame at 950°C for 3 hours, cables powered
2. Fire with Water: Category W• Flame at 650°C for 15 minutes then flame and
water spray for 15 minutes
3. Fire with Mechanical shock: Category Z• Flame at 950°C with mechanical shock applied
at 15s intervals for 15minutes
• Note: All fire rated enclosures must be fitted with ceramic terminals
Extreme Fire Resistance Test
• 19kV High Voltage Enclosure (HVJB) coated with K-Mass™ fireproofing• 1100°C for 1 hour
• Tested in accordance with HC fire curve NEK 606
• Under conditions as specified in ASTM E1725 (Section 4) & ASTM E1529 (Section 5)
• Independent test carried out by Intertek and witnessed by Worley Parsons
Preparation for the Test
Fitted with ceramic pillars, side plates and phase separators. Clad with K-Mass™
19kV DC applied for 1 minute without breakdown prior to test
1100°C for 1 hour
• Required furnace temperature reached after 7min and 44 seconds. The test then began
• A constant 4kVDC voltage was maintained for the duration of the test• Leakage was monitored throughout the test • There was no breakdown
After the Test
Some cooling down is required!
Positive Result• Maximum recorded
temperature within the box was 349°C
• After cool down 19kV DC was re-applied and the enclosure passed

High Voltage Enclosures
Ex-Rated High Voltage Enclosures
• Ex certified HV range based on SX enclosure• From 3.3kV up to 45kV and
3.2kA• Suitable for -50°C• Typical applications:
• Umbilical connection• Down hole pumps• Water injection pumps• Fire suppression systems• Temporary power supply
connections
HV Splitter Box• A unique solution for the
termination of offshore umbilical cables or onshore distribution systems • The power conductor
compartment houses the HV cables • A separate control
compartment is used for terminating fibre optic or control cables• Ex e or Ex e op is• Other ratings same as HVJB
