Polyethylene Pin Type Insulators – Tie-Top
Description:
Hendrix Tie-Top insulators are molded of proprietary, gray, track resistant, high density polyethylene. They are ideal for
use with covered conductors because the low dielectric constant matches that of Hendrix and other polyethylene conductor
insulating compounds. In addition, Hendrix Tie-Top insulators may be used with bare conductors. They are
designed with standard ANSI neck sizes and will fit on standard 1” or 1 3/8” pins. Insulators are available with ratings
of 15kV, 25kV or 35kV.
Benefits:
HPI-15 HPI-25 HPI-35
• Electrically compatible with covered conductors - no stripping is required
• Resistant to impact damage, breakage and vandalism
• Excellent weather washing characteristics
• Interchangeable with porcelain insulators
• Excellent weatherability proven by 25 years of field experience
• Designed for use with hand wrapped ties or preshaped ties
• Light weight for easy handling
• Excellent for contaminated environments
Application:
Hendrix Tie-Top insulators are recommended for use on spacer cable construction at angles and for open wire construction
with either covered conductors or bare conductors. Using polyethylene insulators avoids the problem
of increased corona and the resulting erosion of covered conductors that can occur with porcelain insulators. Hendrix
polyethylene insulators are especially well suited to areas with a history of vandalism. Ballistics tests have shown that
even with damage from rifle or shotgun fire, the insulators were still able to operate. Hendrix polyethylene insulators
are also excellent for contaminated environments due to their long leakage distance and washing characteristics.
When using Hendrix Tie-Top insulators with covered conductors, a covered tie wire is required to prevent erosion
of the conductor covering. Hendrix thermoplastic rubber covered tie wire is available for this purpose. When using
Hendrix Tie-Top insulators with bare conductors, a bare tie wire should be used.

Polyethylene Pin Type Insulators – Data
B-1 Torque Bolt, HT-1 Hook Tool
Electrical, Mechanical & Physical Data:
Characteristic
When ordering Vise-Top insulators, specify the suffix “P” for covered conductors and bare copper conductors
or “M” for bare aluminum conductors.
* Different pin hole diameters and thread configurations to meet international standards are available upon request.
**Review design performance data before using on bare wire systems.
B-1 Torque Bolt:
The B-1 torque bolt may be purchased
separately for replacement purposes. It
is made of black nylon and is designed
to be tightened using the break-away ring.
This ensures proper gripping force on
the conductor. The B-1 torque bolt fits
all Vise-Top insulators. A new torque
bolt should be used when a conductor
is removed and re-installed in an insulator.

HT-1 Hook Tool:
The HT-1 Hook Tool is for quick
tightening of the Torque Bolts on
Vise-Top Insulators on de-energized
circuits. It snaps into most hydraulic
impact wrenches and other tools
used in aerial bucket trucks. The tool
should be operated at slow speed.

Polyethylene Pin Type Insulators – Vise-Top
Description:
Hendrix Vise-Top insulators are a labor saving alternative to Tie-Top insulators. When used with the VTST-1 Stringing
Tool, conductors can be installed without separate stringing blocks. The built-in clamp secures the conductor in the top
or side position, eliminating the need for tie wire. Vise-Top insulators are molded of proprietary gray, track resistant,
high density polyethylene. They are ideal for use with covered conductors because the low dielectric constant of the
polyethylene matches that of Hendrix and other polyethylene insulating compounds. In addition, Hendrix offers
Vise-Top insulators with aluminum clamping inserts for use with bare conductors. They are designed to fit on standard
1” or 1 3/8” pins. Insulators are available with ratings of 15kV, 25kV or 35kV.
Benefits:
HPI-15VTP HPI-25VTP
• Quick and easy installation using two torque bolts
• Torque bolt ring breaks off at a predetermined torque
to provide proper clamping force
• Insulator acts as a stringing block when used with the
VTST-1 stringing tool, significantly reducing installation costs
• Electrically compatible with covered conductors,
no stripping is required
• Resistant to impact damage, breakage and vandalism
• Excellent weather washing characteristics
• Interchangeable with porcelain insulators
• Excellent weatherability proven by 25 years of field experience
• Light weight for easy handling
• Excellent for contaminated environments

There are two types of Vise-Top insulators. One type has nylon clamping inserts for covered conductors and
bare copper conductors. The other type has aluminum clamping inserts for bare aluminum conductors. To specify
Vise-Top insulators with nylon clamping inserts, add the suffix “P” (ex. HPI-15 VTP). For metal clamping inserts, add
the suffix ”M“ (ex. HPI-15VTM).
